2 programming-using-java how to built applicationMahmoud Alfarra
This document discusses key concepts in programming using Java, including:
1. The programming life cycle consists of five stages: thinking, planning, designing, coding, and testing.
2. Algorithms can be represented through pseudo code and flow charts to document solutions before coding.
3. Several examples of algorithms are provided to calculate averages, check conditions, and iterate through loops.
This document is a lecture on decision making practices in Java. It identifies errors in code snippets involving if/else statements and while loops. It also contains examples to trace code with variables and determine output based on variable values. The document is in Arabic and English and presented by Mahmoud R. Alfarra on using Java and correcting errors in code involving conditional and iterative structures.
This document discusses the ternary operator in programming. It defines the ternary operator as an operator that takes three arguments: a comparison, a result for if the comparison is true, and a result for if the comparison is false. It explains the syntax and purpose of the ternary operator, which is to shorten simple if/else statements into a single line of code. An example program is provided to demonstrate how the ternary operator works.
This document provides an overview of control structures in Visual Basic. It describes the three types of control structures: sequence, selection, and iteration. Sequence refers to the default sequential execution of statements. Selection structures like If/Then/Else and Select Case allow branching program execution based on conditions. Iteration structures like For/Next loops and Do/Loop statements allow repeating a block of code until a condition is met. The document provides details and syntax examples for If/Then/Else, Select Case, For/Next loops, and Do/Loop in Visual Basic.
Operators and control statements in Java allow programmers to perform mathematical operations, make logical comparisons, and control program flow. The document discusses the different types of operators in Java including arithmetic, relational, logical, assignment, and ternary operators. It also covers the different types of control statements for decision making (if, if-else, switch) and looping (while, for, do-while loops). Examples are provided to illustrate how each operator and control statement is used.
This lab discusses selections and provides examples of if statement, nested if, and switch. It also covers logical operators and relational operators. It gives many examples to help the student develop logical think and structure computer logic.
This document discusses decision making statements in Visual Basic. It describes two main types of decision making statements: IF statements and Select Case statements.
The IF statement performs one of two possible code actions depending on the result of a comparison. It can be a simple IF, IF Else, or nested IF. The Select Case statement is used for multiple conditional statements and is better than nested IF statements when there are many conditions to check. Both IF and Select Case statements use comparison operators to evaluate conditions and determine which code to execute.
Control statements in C allow changing the order of execution based on conditions or repeating a group of statements. The main types of control statements are selection structures like if/else which execute one or the other block based on a condition being true or false, and looping structures like while, do-while and for loops which repeat a block of code either indefinitely or a specified number of times. Nested loops can also be used to repeat blocks of code multiple times in both the inner and outer loops.
There are three types of errors in programming: syntax errors, run-time errors, and logic errors. Syntax errors occur when code violates rules and prevent programs from running. Run-time errors are unpredictable and can be trapped using error handling. Logic errors produce unexpected results and are hardest to find, requiring debugging tools. Visual Basic provides debugging aids like breakpoints, stepping, and watch expressions to help locate logic errors.
By the end of this chapter, students will be able to:
Explain the operation of if, else if and else
Explain the operation of relational and logical operators
Analyze programs that use branching
Write programs that use branching to solve problems

Exception handling in c++ by manoj vasavaManoj_vasava
Exception handling in C++ provides built-in features to detect and handle runtime errors such as division by zero or accessing arrays out of bounds. Exceptions are unusual conditions that may occur during program execution and exception handling provides a type-safe way to cope with unpredictable problems at runtime rather than terminating the program. Exception handling is needed for object-oriented and distributed programs because traditional error handling solutions are not always appropriate.
This document summarizes three types of decision making statements in VB.NET: If...Then, If...Then...Else, and Select Case. It provides the syntax and examples of each statement type. The If...Then statement executes code if a condition is true, while If...Then...Else executes one set of code if true and another if false. Select Case checks a variable against multiple potential values and executes the code for the matching value.
Exception handling in Java allows programmers to manage runtime errors programmatically. The try block contains code that may throw exceptions, while catch blocks define how to handle specific exceptions. Finally blocks contain cleanup code that always executes regardless of exceptions. Common exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and ArithmeticException. The throw keyword explicitly throws exceptions, while throws in method declarations informs callers about checked exceptions they must handle or propagate.
The document discusses control structures in Java, including selection statements like if-else and switch statements, and iteration statements like for, while, do-while loops. It provides examples and explanations of how each statement works. Key points covered include how if-else statements evaluate conditions and execute the appropriate block, how switch statements can be used as a replacement for long if-else-if chains, and how the different loop constructs like for, while, do-while iterate until a condition is met. It also discusses concepts like break, continue and return which change the flow of control.

The document discusses the steps for creating classes and routines in programming. It describes creating an initial design for the class or routine using pseudocode. The key steps are to design the routine, code it, check the code, clean up leftover issues, and repeat the process as needed. Pseudocode uses English-like statements to precisely describe operations at a level of intent that is easily translatable to code.
In this lab you will learn how to use the Java Software Development Kit (SDK) with the Eclipse programming tool. In addition, you will create three simple Java programs.
The document discusses switch case statements in C programming. It explains that switch case statements provide an alternative to long if-else statements by allowing a variable to be compared to multiple integer values. The program flow will continue at the case matching the variable's value. Break statements are used to exit each case block. A default case can handle any non-matching values. Examples are provided to demonstrate how switch case statements can be used to process user input and perform simple mathematical operations based on the input.
This chapter discusses:
1. Program flow control and statements like conditionals and loops that alter normal linear execution.
2. Conditional statements like if/else that allow choosing which statement executes based on a boolean condition.
3. Repetition statements like while and for loops that repeatedly execute a statement as long as/for as long as a condition is true.
Chapter 3 introduces several Java program statements:
- Conditional statements like if-else allow programs to make decisions based on boolean expressions.
- Loops like while and for allow code to repeat based on conditions.
- Logical operators like && and || combine boolean expressions.
- Proper program design is important, involving requirements, design, implementation, and testing stages.

- Conditional statements like if, if-else, and switch that allow modifying the flow of control through a method.
- Logical operators like && and || that can be used to form complex boolean expressions for conditionals.
The document discusses different types of selection statements in C including if, if-else, and switch statements. Relational expressions are used to create conditions for if statements and can be combined using logical operators. An if statement executes a statement if a condition is true, while an if-else statement chooses between two statements depending on the condition. Nested if-else statements and switch statements provide multiway selection. Common errors include misusing assignment versus relational operators and failing to use braces with nested if statements.
This document teaches how to write Small Basic programs using conditions and loops, including using if/then/else statements to execute different code depending on logical conditions, and for, while, and step loops to repeat blocks of code a set number of times or until a condition is met. Examples are provided of programs that check even/odd numbers, print multiplication tables, and demonstrate increasing a counter by more than 1 each loop iteration using step. The document concludes by having the reader write a program to convert student scores to letter grades.
The document discusses different types of if statements in C programming. It describes the basic if statement syntax which executes a statement if a condition is true. It also covers the if-else statement which executes one block of code if the condition is true and another block if false. Else-if clauses allow checking multiple conditions. Logical operators like &&, || and ! can be used to combine conditions. Nested if statements allow if-else blocks within other if/else blocks. Examples are provided to demonstrate calculating discounts, employee bonuses, student grades and more using if and if-else statements.

Here is a complete representation of using if else conditions, logical operators and switch statements using c++ language. After learning this you will be able to solve problems involving conditional statement and logical operators. Moreover, you will also be able to make switch statements.
Paired comparison analysis involves comparing options two at a time and scoring which is preferred. This technique can be used to evaluate employees, prioritize projects, or choose between solutions. A matrix is created where each option is compared to every other option, scoring which is better. Scores are totaled to determine an overall preferred option. While useful for setting priorities without objective data, disadvantages include employee comparability issues and lack of sufficient rater knowledge for employee evaluations.

Case Study 1:
Should a Computer Grade Your Essays?
Would you like your college essays graded by a computer? Well, you just might find that happening in your next course. In April 2013, EdX, a Harvard/MIT joint venture to develop massively open online courses (MOOCs), launched an essay-scoring program. Using artificial intelligence technology, essays and short answers are immediately scored and feedback tendered, allowing students to revise, resubmit, and improve their grade as many times as necessary. The non-profit organization is offering the software free to any institution that wants to use it. From a pedagogical standpoint—if the guidance is sound—immediate feedback and the ability to directly act on it is an optimal learning environment. But while proponents trumpet automated essay grading's superiority to students waiting days or weeks for returned papers— which they may or may not have the opportunity to revise—as well as the time-saving benefit for instructors, critics doubt that humans can be replaced.
In 2012, Les Perelman, the former director of writing at MIT, countered a paper touting the proficiency of automated essay scoring (AES) software. University of Akron College of Education dean, Mark Shermis, and co-author, data scientist Ben Hamner used AES programs from nine companies, including Pearson and McGraw-Hill, to rescore over 16,000 middle and high school essays from six different state standardized tests. Their Hewlett Foundation sponsored study found that machine scoring closely tracked human grading, and in some cases, produced a more accurate grade. Perelman, however, found that no direct statistical comparison between the human graders and the programs was performed. While Shermis concedes that regression analysis was not performed—because the software companies imposed this condition in order to allow him and Hamner to test their products—he unsurprisingly accuses Perelman of evaluating their work without performing research of his own.
Perelman has in fact conducted studies on the Electronic Essay Rater (e-rater) developed by the Educational Testing Service (ETS)—the only organization that would allow him access. The e-rater uses syntactic variety, discourse structure (like PEG) and content analysis (like IEA) and is based on natural language processing technology. It applies statistical analysis to linguistic features like argument formation and syntactic variety to determine scores, but also gives weight to vocabulary and topical content. In the month granted him, Perelman analyzed the algorithms and toyed with the e-Rater, confirming his prior critiques. The major problem with AES.

This document provides details about a case study assignment for a management information systems course. It includes guidelines for completing four individual case study analyses over the semester. Each case study includes 3-5 multiple choice questions worth 1 mark each. The questions assess understanding of concepts from the readings and their application to the case studies. Topics covered in the case studies include automated essay grading systems, data management at an water utility company, and use of analytics and data management software at a fleet management company. Students will also present a summary of their analysis of one case study.
The document discusses the different types of operators in Java including arithmetic, unary, assignment, relational, logical, ternary, and bitwise operators. It provides examples and brief explanations of each type of operator. Arithmetic operators are used for mathematical operations. Unary operators operate on a single operand. Assignment operators assign values to variables. Relational operators test relations between entities. Logical operators are used to combine conditional statements. The ternary operator is a one-line replacement for if-then-else statements. Bitwise operators perform bit-level manipulation of numeric values.
One of the most important issues that organizations have to deal with is the timely identification and detection of risk factors aimed at preventing incidents. Managers’ and engineers’ tendency towards minimizing risk factors in a service, process or design system has obliged them to analyze the reliability of such systems in order to minimize the risks and identify the probable errors. Concerning what was just mentioned, a more accurate Failure Mode and Effects Analysis (FMEA) is adopted based on fuzzy logic and fuzzy numbers. Fuzzy TOPSIS is also used to identify, rank, and prioritize error and risk factors. This paper uses FMEA as a risk identification tool. Then, Fuzzy Risk Priority Number (FRPN) is calculated and triangular fuzzy numbers are prioritized through Fuzzy TOPSIS. In order to have a better understanding toward the mentioned concepts, a case study is presented.
This document provides an outline and overview of hashing and hash tables. It defines hashing as a technique for storing data to allow for fast insertion, retrieval, and deletion. A hash table uses an array and hash function to map keys to array indices. Collision resolution techniques like linear probing are discussed. The document also summarizes the Hashtable class in .NET, which uses buckets and load factor to avoid collisions. Examples of hash functions and using the Hashtable class are provided.
This document discusses graphs and their representation in code. It defines graphs as consisting of vertices and edges, with edges specified as pairs of vertices. It distinguishes between directed and undirected graphs. Key graph terms like paths, cycles, and connectivity are defined. Real-world systems that can be modeled as graphs are given as an example. The document then discusses representing vertices and edges in code, choosing an adjacency matrix to represent the edges in the graph.
The document discusses trees and binary trees as data structures. It defines what a tree is, including parts like the root, parent, child, leaf nodes. It then defines binary trees as trees where each node has no more than two children. Binary search trees are introduced as binary trees where all left descendants of a node are less than or equal to the node and all right descendants are greater. The document concludes by discussing how to build a binary search tree class with Node objects.
This document provides an outline and overview of the queue data structure. It defines a queue as a first-in, first-out (FIFO) structure where new items are added to the rear of the queue and items are removed from the front. The key queue operations of enqueue and dequeue are described. Code examples are provided for implementing a queue using a linked list structure with classes for the queue, its nodes, and methods for common queue operations like enqueue, dequeue, peek, clear, print, and search. Different types of queues like linear, circular, and double-ended queues are also mentioned.
The document provides an overview of stack data structures, including definitions and examples. It discusses key stack operations like push, pop, peek, clear, print all, and search. Code examples are given for an Employee class and Stack class implementation to demonstrate how these operations work on a stack of employee objects. The document aims to teach the fundamentals of stack data structures and provide code samples to practice stack operations.
This document provides an outline and overview of linked lists. It defines a linked list as a collection of nodes that are linked together by references to the next node. Each node contains a data field and a reference field. It describes how to implement a linked list using a self-referential class with fields for data and a reference to the next node. It then outlines common linked list operations like insertion and deletion at different positions as well as sorting and searching the linked list.
Chapter 4: basic search algorithms data structureMahmoud Alfarra
1) The document discusses two common search algorithms: sequential search and binary search. Sequential search looks at each item in a list sequentially until the target is found. Binary search works on a sorted list and divides the search space in half at each step.
2) It provides pseudocode examples of how each algorithm works step-by-step to find a target value in a list or array.
3) Binary search is more efficient than sequential search when the list is sorted, as it can significantly reduce the number of comparisons needed to find the target. Sequential search is used when the list is unsorted.
Chapter 3: basic sorting algorithms data structureMahmoud Alfarra
The document provides an outline and introduction for a chapter on basic sorting algorithms, including bubble sort, selection sort, and insertion sort algorithms. It includes pseudocode examples and explanations of each algorithm. It notes that bubble sort is one of the slowest but simplest algorithms, involving values "floating" to their correct positions. Selection sort finds the smallest element and places it in the first position, then repeats to find the next smallest. Insertion sort works by moving larger elements to the right to make room for smaller elements inserted from the left.

Graph-Based Technique for Extracting Keyphrases In a Single-Document (GTEK)Mahmoud Alfarra
This paper is the best one in the DataMining session in the ICPET 2018.
Paper about:
Graph-based Technique for Extracting Keyphrases in a single document (GTEK) is introduced.
GTEK is based on the graph-based representation of text.
GTEK motivated by:
A phrase may be important if it appears in the most important sentences in the document.
The Most important KP must cover all sub-topics of document.
GTEK groups the sentences into graph-model clusters. Then ranks them using TextRank algorithm.
Finally, the most frequent phrases in the high ranked sentences are selected as document keyphrases.

The *nervous system of insects* is a complex network of nerve cells (neurons) and supporting cells that process and transmit information. Here's an overview:
Structure
1. *Brain*: The insect brain is a complex structure that processes sensory information, controls behavior, and integrates information.
2. *Ventral nerve cord*: A chain of ganglia (nerve clusters) that runs along the insect's body, controlling movement and sensory processing.
3. *Peripheral nervous system*: Nerves that connect the central nervous system to sensory organs and muscles.
Functions
1. *Sensory processing*: Insects can detect and respond to various stimuli, such as light, sound, touch, taste, and smell.
2. *Motor control*: The nervous system controls movement, including walking, flying, and feeding.

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder
Introduction
All the materials around us are made up of elements. These elements can be broadly divided into two major groups:
Metals
Non-Metals
Each group has its own unique physical and chemical properties. Let's understand them one by one.
Physical Properties
1. Appearance
Metals: Shiny (lustrous). Example: gold, silver, copper.
Non-metals: Dull appearance (except iodine, which is shiny).
2. Hardness
Metals: Generally hard. Example: iron.
Non-metals: Usually soft (except diamond, a form of carbon, which is very hard).
3. State
Metals: Mostly solids at room temperature (except mercury, which is a liquid).
Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid).
4. Malleability
Metals: Can be hammered into thin sheets (malleable).
Non-metals: Not malleable. They break when hammered (brittle).
5. Ductility
Metals: Can be drawn into wires (ductile).
Non-metals: Not ductile.
6. Conductivity
Metals: Good conductors of heat and electricity.
Non-metals: Poor conductors (except graphite, which is a good conductor).
7. Sonorous Nature
Metals: Produce a ringing sound when struck.
Non-metals: Do not produce sound.
Chemical Properties
1. Reaction with Oxygen
Metals react with oxygen to form metal oxides.
These metal oxides are usually basic.
Non-metals react with oxygen to form non-metallic oxides.
These oxides are usually acidic.
2. Reaction with Water
Metals:
Some react vigorously (e.g., sodium).
Some react slowly (e.g., iron).
Some do not react at all (e.g., gold, silver).
Non-metals: Generally do not react with water.
3. Reaction with Acids
Metals react with acids to produce salt and hydrogen gas.
Non-metals: Do not react with acids.
4. Reaction with Bases
Some non-metals react with bases to form salts, but this is rare.
Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc).
Displacement Reaction
More reactive metals can displace less reactive metals from their salt solutions.
Uses of Metals
Iron: Making machines, tools, and buildings.
Aluminum: Used in aircraft, utensils.
Copper: Electrical wires.
Gold and Silver: Jewelry.
Zinc: Coating iron to prevent rusting (galvanization).
Uses of Non-Metals
Oxygen: Breathing.
Nitrogen: Fertilizers.
Chlorine: Water purification.
Carbon: Fuel (coal), steel-making (coke).
Iodine: Medicines.
Alloys
An alloy is a mixture of metals or a metal with a non-metal.
Alloys have improved properties like strength, resistance to rusting.
APM event hosted by the Midlands Network on 30 April 2025.
Speaker: Sacha Hind, Senior Programme Manager, Network Rail
With fierce competition in today’s job market, candidates need a lot more than a good CV and interview skills to stand out from the crowd.
Based on her own experience of progressing to a senior project role and leading a team of 35 project professionals, Sacha shared not just how to land that dream role, but how to be successful in it and most importantly, how to enjoy it!
Sacha included her top tips for aspiring leaders – the things you really need to know but people rarely tell you!
We also celebrated our Midlands Regional Network Awards 2025, and presenting the award for Midlands Student of the Year 2025.
This session provided the opportunity for personal reflection on areas attendees are currently focussing on in order to be successful versus what really makes a difference.
Sacha answered some common questions about what it takes to thrive at a senior level in a fast-paced project environment: Do I need a degree? How do I balance work with family and life outside of work? How do I get leadership experience before I become a line manager?
The session was full of practical takeaways and the audience also had the opportunity to get their questions answered on the evening with a live Q&A session.
Attendees hopefully came away feeling more confident, motivated and empowered to progress their careers

Forgetting the left and/or right parentheses for the condition
in an if statement is a syntax error the parentheses are
required.
Confusing the equality operator, ==, with the assignment
operator, =, can cause a logic error or a syntax error.
It is a syntax error if the operators ==, !=, >= and <= contain
spaces between their symbols, as in = =, ! =, > = and < =,
respectively.
Reversing the operators !=, >= and <=, as in =!, => and =<, is
a syntax error.
