JAVA AWTshanmuga rajan

javascript objectsVijay Kalyan

Objects in JavaScript can be created using object literals, the new keyword, or Object.create(). Objects are collections of properties and methods that are mutable and manipulated by reference. Arrays are objects that represent ordered collections of values of any type and are created using array literals or the Array constructor. Common array methods include concat, join, pop, push, reverse, and sort. The Math object provides common mathematical functions like pow, round, ceil, floor, random, and trigonometric functions.

StackZaid Shabbir

A stack is a data structure where items can only be inserted and removed from one end. The last item inserted is the first item removed (LIFO). Common examples include stacks of books, plates, or bank transactions. Key stack operations are push to insert, pop to remove, and functions to check if the stack is empty or full. Stacks can be used to implement operations like reversing a string, converting infix to postfix notation, and evaluating arithmetic expressions.

Java- Nested ClassesPrabhdeep Singh

An inner class is a class declared within another class. There are several types of inner classes including local inner classes and anonymous inner classes. Local inner classes cannot be invoked from outside the method they are declared in and can only access final parameters of the enclosing block. Anonymous inner classes are used when a local class is only needed once and help make code more concise by allowing declaration and instantiation at the same time. The .this operator refers to the current instance of the enclosing class from within an inner class. The .new operator is used to create an object of the inner class type by specifying the enclosing class instance. Inner classes increase encapsulation and can lead to more readable code by placing related classes closer together.

Aggregate functionssinhacp

This document discusses aggregate functions in SQL. It defines aggregate functions as functions that summarize expression results over multiple rows into a single value. Commonly used aggregate functions include SUM, COUNT, AVG, MIN, and MAX. Examples are provided calculating sums, averages, minimums, and maximums of salaries in an employee table to illustrate the use of these functions. It also discusses issues like ignoring null values and the need to use the GROUP BY clause with aggregate functions.

Basics of JavaScriptBala Narayanan

JavaScript is a scripting language originally designed for web browsers but now used everywhere. It has dynamic typing and supports object-oriented, imperative, and functional programming. JavaScript was created in 1995 and standardized in 1999. It is now the most popular language on GitHub. JavaScript can be used to build interactive web pages, desktop applications, server-side applications, IoT applications, and real-time applications. The core data types in JavaScript are Number, String, Boolean, Object, Function, Array, Date, and Regular Expressions. JavaScript supports features like variables, flow control, error handling, debugging, and JSON for data exchange.

Oracle: Control StructuresDataminingTools Inc

This document discusses various control structures and loops in Oracle including simple loops, while loops, for loops, nested loops, and selective statements like if, if/else, if/elsif/else, and case. Loops allow iterating through a block of code until a condition is met. Control structures alter program flow. Nested loops allow looping within other loops. Selective statements perform actions conditionally based on evaluated conditions.

08 c++ Operator Overloading.pptTareq Hasan

Operator overloading allows operators like + and << to be used with user-defined types like classes. It is done by defining corresponding operator functions like operator+() and operator<<(). This allows objects to be used with operators in a natural way while providing custom behavior for that type. The rules for overloading include maintaining precedence and associativity of operators. Common operators like +, -, *, /, <<, >>, ==, =, [] and () can be overloaded to allow user-defined types to work with them.

[OOP - Lec 19] Static Member FunctionsMuhammad Hammad Waseem

Static member functions can be accessed without creating an object of the class. They are used to access static data members, which are shared by all objects of a class rather than each object having its own copy. The examples show declaring a static data member n and static member function show() that prints n. show() is called through the class name without an object. Each object creation in the constructor increments n, and show() prints the updated count.

Classes objects in javaMadishetty Prathibha

The document discusses key concepts in Java including classes, objects, methods, and command line arguments. A class defines common properties and behaviors for objects through fields and methods. Objects are instantiated from classes and can access fields and methods using dot notation. Command line arguments allow passing data into a Java application and are accessed through the args parameter in the main method.

This pointerKamal Acharya

This document discusses different uses of the "this" pointer in C++ classes. This pointer points to the object whose member function is being called. It can be used to return the object from a member function, access the memory address of the object, and access data members within member functions. Sample programs are provided to demonstrate returning an object using this, displaying the memory address of an object using this, and accessing a data member within a member function using this->.

Java layoutmanagerArati Gadgil

The document discusses different layout managers in Java including BorderLayout, GridLayout, FlowLayout, CardLayout, and BoxLayout. BorderLayout arranges components in five regions (north, south, east, west, center) with one component per region. GridLayout arranges components in a rectangular grid with the same number of components per row. FlowLayout arranges components in a line, one after another. CardLayout displays one component at a time, treating each like a card. BoxLayout arranges components along an axis.

Aggregate functionRayhan Chowdhury

Aggregate functions are functions that take a collection of values as input and return a single value.The ISO standard defines five (5) aggregate functions namely :- 1) COUNT 2) SUM 3) AVG 4) MIN 5) MAX 1.COUNT Function The COUNT function returns the total number of values in the specified field. It works on both numeric and non-numeric data types. All aggregate functions by default exclude nulls values before working on the data. MIN function The MIN function returns the smallest value in the specified table field. 2.MAX function Just as the name suggests, the MAX function is the opposite of the MIN function. It returns the largest value from the specified table field. 3.SUM function Suppose we want a report that gives total amount of payments made so far. We can use the MySQL SUM function which returns the sum of all the values in the specified column. SUM works on numeric fields only. Null values are excluded from the result returned. 4.AVG function MySQL AVG function returns the average of the values in a specified column. Just like the SUM function, it works only on numeric data types. 5.MIN function The MIN function returns the smallest value in the specified table field.

Php formsAnne Lee

The document discusses PHP forms and includes the following key points: 1. Forms can submit data via GET and POST methods, with GET appending data to the URL and POST transmitting data hiddenly. Both methods store data in superglobal arrays ($_GET and $_POST). 2. Form validation ensures required fields are filled and data meets specified criteria. Common validations check for required fields, valid email addresses, URLs, and more. 3. HTML form elements like text fields, textareas, radio buttons, drop-downs are used to collect user input. PHP processes submitted data and can validate required fields are not empty.

Inheritance in JAVA PPTPooja Jaiswal

This document discusses inheritance in object-oriented programming. It defines inheritance as establishing a link between classes that allows sharing and accessing properties. There are three types of inheritance: single, multilevel, and hierarchical. Single inheritance involves one parent and one child class, multilevel inheritance adds intermediate classes, and hierarchical inheritance has one parent and multiple child classes. The document provides examples of inheritance code in Java and demonstrates a program using inheritance with interfaces. It notes some limitations of inheritance in Java.

Type casting in javaFarooq Baloch

Type casting involves assigning a value of one data type to a variable of another type. There are two types of casting: widening (implicit) and narrowing (explicit). Widening casting converts data to a broader type without needing explicit casting, like converting an int to a long. Narrowing casting converts to a narrower data type and requires explicit casting, such as converting a double to a long.

Mysql Crud, Php Mysql, php, sqlAimal Miakhel

This document discusses CRUD operations in MySQL and database design. It explains that tables contain records made of columns/fields that classify data. Common data types like varchar, char, int, float, datetime are described. CRUD stands for Create, Read, Update, Delete - the basic functions to add, retrieve, modify and remove data in a database. Examples of SQL queries like SELECT, INSERT, UPDATE, DELETE are provided to demonstrate CRUD operations on a sample Users table. Additional SQL clauses like WHERE, BETWEEN, IN, LIKE, GROUP BY, COUNT, SUM are also overviewed.

ArraysNotre Dame of Midsayap College

Traffic safetyThen Murugeshwari

Fermilab observes Illinois traffic safety rules and has identified five factors contributing to most on-site vehicle accidents: improper backing, hazardous weather, distracted driving, speeding, and improper road sharing. Fermilab employs corrective actions for violations which are detailed in its ES&H Manual. The document provides tips for safe driving practices including proper backing techniques, winter driving preparedness, avoiding distractions, maintaining safe speeds, and sharing the road courteously with bicycles and motorcycles.

P h indicatorsThen Murugeshwari

The document discusses pH indicators and their uses in titration. It provides information on the pH ranges and color changes of common acid-base indicators like methyl orange, methyl red and bromthymol blue. It also lists the ideal properties of pH sensors and describes how different indicators are used to titrate strong acids and bases or weak acids and bases. Common natural pH indicators from foods like red cabbage, beet and blueberries are also mentioned.

Avogadro's lawThen Murugeshwari

Avogadro's law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. It provided a rational explanation for Gay-Lussac's law of combining volumes and indicated that elemental gases like hydrogen and chlorine exist as diatomic molecules. Avogadro's law also established a method for determining molecular weights of gases and helped develop the kinetic molecular theory. According to the law, if the amount of gas is increased or decreased, the volume will change proportionally.

ResonanceThen Murugeshwari

Resonance refers to the tendency of a system to oscillate at specific resonant frequencies, where even small periodic driving forces can produce large oscillations. These resonant frequencies depend on properties like the size and material of the system. Standing waves can be produced in a closed tube when pressure pulses are emitted at the tube's resonant frequencies, reinforcing the vibration and allowing it to continue resonating. The longer the tube, the lower the resonant frequencies will be.

Microwave remote sensingThen Murugeshwari

The document discusses the history and applications of microwave remote sensing. It began with US military research after World War II and studies by NASA in the 1960s to use microwave technology for earth observation. Key developments included airborne and spaceborne sensors to measure surface scattering properties and models to explain microwave interactions with natural targets. Current applications of microwave remote sensing include weather monitoring, navigation, imaging, and mapping for both civilian and military uses.

Newton's lawThen Murugeshwari

- Aristotle believed that objects have a natural place and will return to that place after being moved by force. Isaac Newton later proposed that objects tend to stay in their current state of motion unless acted on by an unbalanced force. - Newton published his three laws of motion in 1687, including the first law that an object at rest or in motion stays at rest or in motion unless acted on by an outside force. - Forces can be contact forces that require touching an object or long-range forces like gravity that act over a distance. Forces have agents that are the direct cause of the force.

Surface tensionThen Murugeshwari

Surface tension is caused by the attraction between water molecules at the surface of a water droplet or body of water. This attraction creates tension at the surface. The tension acts like a elastic sheet or skin that tries to minimize the surface area to reduce the energy of the system. For small objects or insects, surface tension can allow them to float or walk on water by supporting their weight through tension along their contact perimeter. Contact angle is the angle formed between a liquid surface and the solid surface it contacts and depends on a balance of forces from surface tensions and adhesive/repulsive forces between the liquid and solid.

Hook's lawThen Murugeshwari

Hooke's Law describes the relationship between the force applied to an unstretched spring and the amount it is stretched. It states that the extension of a spring is directly proportional to the applied force. An experiment is described where different masses are hung from a spring to determine its extension at increasing forces. A graph of force versus extension results in a straight line, showing springs obey Hooke's Law up to their elastic limit. Beyond this point, springs undergo plastic deformation and do not return to their original length when force is removed.

Hook's lawThen Murugeshwari

Hooke's Law describes the relationship between the force applied to an unstretched spring and the amount it is stretched. An experiment is conducted to determine how the extension of a spring varies with the stretching force. Weights are added to a spring in stages and the extension is measured. The results show that the extension is directly proportional to the applied force, as predicted by Hooke's Law, but only up to a certain point known as the elastic limit. Beyond this point, the spring undergoes plastic deformation and does not return to its original length when the force is removed.

ERP componentsThen Murugeshwari

ERP software consists of several key components that represent major functional areas of an organization. These components include financial management, manufacturing, human resources, materials management, production planning, plant maintenance, purchasing, marketing, and sales and distribution. Each component handles important tasks like managing finances, production processes, employee information, inventory, purchasing, and sales.

Database fundamentalsThen Murugeshwari

This document discusses the basics of database management systems (DBMS). It begins by explaining the data storage hierarchy from the bit level up to the database level. It then covers different database models including hierarchical, network, relational, and object-oriented. Key components of a DBMS like DDL, DML, query language, and report generators are defined. Commercial DBMS examples are provided. The document concludes with an overview of creating and using a database, including defining the structure, entering data, and searching for information.

MosfetThen Murugeshwari

A MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a semiconductor device that is commonly used in power electronics. It works by modulating charge concentration between a gate electrode, which is insulated from other device regions by an oxide layer, and a body region. Depending on whether it is an n-channel or p-channel MOSFET, the source and drain regions have either n+ or p+ doping while the body has the opposite doping. Applying a voltage to the gate can turn the channel between source and drain on or off to allow or prevent current flow. MOSFETs can be made with silicon on insulator or other semiconductor materials.

HiperlanThen Murugeshwari

HiperLAN was developed as a wireless local area network standard by ETSI to provide higher data rates than early 802.11 standards. HiperLAN Type 1 achieved data rates up to 2 Mbps for ad hoc networking. HiperLAN Type 2 was later developed to provide connection-oriented service up to 54 Mbps, with quality of service guarantees, security, and flexibility. It uses OFDM in the 5 GHz spectrum for robust transmission. While early products only achieved 25 Mbps, the standard provides a framework for higher speeds as technologies advance. HiperLAN is intended to complement wired networks by providing wireless connectivity in hotspot areas like offices, homes, and public places.

Bluetooth profileThen Murugeshwari

RouterThen Murugeshwari

A router forwards data packets between computer networks based on IP addresses. It examines header information in each packet and determines the best path to send it towards its destination, choosing the route with the lowest cost. Routers work at the IP protocol level and maintain routing tables with information about neighboring routers and the costs of routes to efficiently transmit data packets between networks.

Operators in javaThen Murugeshwari

Thread priorities determine the order threads are executed, with higher priority threads running first. Priorities range from 1 to 10, with 5 as the default. The scheduler allocates CPU time to the highest priority ready thread. Preemptive scheduling allows a new, higher priority thread to interrupt a currently running lower priority thread. For threads of equal priority, round-robin scheduling evenly allocates CPU time slices. The example demonstrates setting thread priorities and the effect on execution order.

ThreadsThen Murugeshwari

The document discusses Java threads and thread synchronization. It defines that a thread is a flow of control and sequence of executed statements. It explains that a Thread is an object that can be created by extending the Thread class or implementing the Runnable interface. The start() method creates and runs the thread, while run() defines the code for the thread to execute. Threads have a lifecycle and can be in different states like ready, running, blocked/waiting. Synchronization is used to coordinate access to shared resources using locks, and wait/notify allows threads to signal and wait for each other.

Virtual groundThen Murugeshwari

A virtual ground is a point in a circuit that has a voltage of 0 volts, but is not directly connected to ground. The document describes two virtual ground circuits using voltage dividers with opposing voltage sources. In the first circuit, the 10V and -10V sources create a 20V difference with a virtual ground at the midpoint. In the second circuit, the 1V and -10V sources create an 11V difference, with the virtual ground again occurring at the midpoint.

Operators

1. Operators in VB.NETwww.ustudy.in

2. IntroductionOperator is defined as a symbol that operates the variables and constants to produce a required result.www.ustudy.in

3. VB.NET OperatorsArithmetic operatorsComparison operatorsLogical operatorsConcatenation operatorswww.ustudy.in

4. Arithmetic operatorsArithmetic operators are used to perform arithmetic calculations such as addition and subtraction.VB.NET supported arithmetic are listed in the given table.www.ustudy.in

5. www.ustudy.in

6. Comparison operatorsComparison operators are used to compare two or more values.VB.NET supported comparison operators are listed in the following table.www.ustudy.in

7. www.ustudy.in

8. Logical operatorsLogical operators are used to perform logical operations such as AND, OR, NOT on one or more expressions.www.ustudy.in

9. ANDThis operator is used as a conjunction of two conditions. The result of the AND operation is True only if both the conditions are true. Syntax:Result = Expression1 AND Expression2www.ustudy.in

10. Result of AND operation tablewww.ustudy.in

11. Example of AND Operator Dim a, b, c As Integer Dim d As Boolean a = 10 b = 20 c = 30d = (a<b) AND (b<c) ‘Returns True’d = (a>b) AND (b<c) ‘Returns False’www.ustudy.in

12. ORThis operator is used as a disjunction of two conditions. The result of the OR operator is false only if both the conditions are false. Syntax:Result = Expression1 OR Expression2www.ustudy.in

13. Result of OR operation tablewww.ustudy.in

14. Example of OR Operator Dim a, b, c As Integer Dim d As Boolean a = 10 b = 20 c = 30d = (a<b) OR (b>c) ‘Returns True’d = (a>b) OR (b>c) ‘Returns False’www.ustudy.in

15. XORThe result this operator is True only if one of the conditions is true and other is false. Syntax:Result = Expression1 XOR Expression2www.ustudy.in

16. Result of XOR operation tablewww.ustudy.in

17. Example of XOR Operator Dim a, b, c As Integer Dim d As Boolean a = 10 b = 20 c = 30d = (a<b) XOR (b<c) ‘Returns False’d = (a>b) XOR (b<c) ‘Returns True’www.ustudy.in

18. NOTThis logical operator is used to perform a logical negation on a boolean expression. Syntax:Result = NOT (boolean Expression)www.ustudy.in

19. Result of NOT operation tablewww.ustudy.in

20. Example of XOR Operator Dim a, b, c As Integer Dim d As Boolean a = 10 b = 20 c = NOT (a>b) ‘Returns True’c = NOT (a<b) ‘Returns False’www.ustudy.in

21. AndAlsoThis operator is same as AND operator but if the first condition is false then the second condition is not checked and the result is false. Syntax:Result = Expression 1 AndAlso Expression2www.ustudy.in

22. OrElseThis operator is same as OR operator but if the first condition is true then the second condition is not checked and the result is True. Syntax:Result = Expression 1 OrElse Expression2www.ustudy.in

23. Concatenation operatorsConcatenation operators are used to join two string values. & and + are the two concatenation operators available in VB.NET.The operator & is used to concatenate two strings and + is used to add two numbers and concatenate two strings. www.ustudy.in

24. Example of concatenation operatorsMsgBox(“Good” & “Night”) ‘Returns GoodNight’MsgBox(“Good” + “Night”) ‘Returns GoodNight’MsgBox(“22” & “33”) ‘Returns 2233’MsgBox(“22” + “33”) ‘Returns 2233’MsgBox(22 + 33) ‘Returns 55’www.ustudy.in
