This document discusses Java strings and provides information about: 1. What strings are in Java and how they are treated as objects of the String class. Strings are immutable. 2. Two ways to create String objects: using string literals or the new keyword. 3. Important string methods like concatenation, comparison, substring, and length; and string classes like StringBuffer and StringBuilder that allow mutability.

Tree - Data StructureAshim Lamichhane

This document provides an overview of trees as a non-linear data structure. It begins by discussing how trees are used to represent hierarchical relationships and defines some key tree terminology like root, parent, child, leaf, and subtree. It then explains that a tree consists of nodes connected in a parent-child relationship, with one root node and nodes that may have any number of children. The document also covers tree traversal methods like preorder, inorder, and postorder traversal. It introduces binary trees and binary search trees, and discusses operations on BSTs like search, insert, and delete. Finally, it provides a brief overview of the Huffman algorithm for data compression.

GIT is a free and open source distributed version control system that allows developers to work collaboratively without needing centralized connectivity. It provides powerful branching capabilities that allow creating branches cheaply and merging them easily. Common GIT commands include init, clone, status, add, commit, log, remote, fetch, push, and pull. An example scenario demonstrates how multiple developers can clone a remote repository, make changes on their local repos, fetch and push changes between local and remote repos, and merge branches.

Linked list in Data Structure and Algorithm KristinaBorooah

Linked listakshat360

Linked lists are linear data structures where each node contains a data field and a pointer to the next node. There are two types: singly linked lists where each node has a single next pointer, and doubly linked lists where each node has next and previous pointers. Common operations on linked lists include insertion and deletion which have O(1) time complexity for singly linked lists but require changing multiple pointers for doubly linked lists. Linked lists are useful when the number of elements is dynamic as they allow efficient insertions and deletions without shifting elements unlike arrays.

Data Structures - Lecture 9 [Stack & Queue using Linked List]Muhammad Hammad Waseem

This document discusses implementing stacks and queues using linked lists. For a stack, elements are inserted and removed from the head (start) of the linked list for constant time operations. For a queue, elements are inserted at the head and removed from the tail (end) of the linked list, requiring traversing to the second last node for removal. Implementing stacks and queues with linked lists avoids size limitations of arrays and uses dynamic memory allocation.

List Data StructureZidny Nafan

A list is a sequential data structure that allows additions and removals at any position, unlike stacks and queues. Common list operations include adding and removing nodes, updating node contents, checking if the list is empty/full, and initializing/destroying the list. Lists can be implemented using arrays (for static storage) or linked nodes (for dynamic storage). Array lists allow constant-time access but linear-time insertion/removal. Linked lists have linear-time access but constant-time insertion/removal. Both use probes and previous references to traverse the list during operations.

sets and mapsRajkattamuri

The document discusses Java Sets and Maps. It describes that a Set is an unordered collection with no duplicates, while a Map maps keys to values with no duplicate keys. Common Set implementations are HashSet, TreeSet, and LinkedHashSet. Common Map implementations are HashMap and TreeMap. The document provides examples of typical operations on Sets like contains, add, remove, and iterating with iterators or enhanced for loops. It also discusses operations on Maps like put, get, remove, and iterating over the keySet, values, or entrySet.

Doubly Linked ListV.V.Vanniaperumal College for Women

Doubly linked lists allow navigation in both directions by linking each node to both the next and previous nodes. Each node contains data and pointers to the next and previous nodes. Operations like insertion and deletion are more complex than with singly linked lists since both next and previous pointers must be updated. However, elements can be easily accessed from either direction. Basic operations on doubly linked lists include insertion and deletion at the beginning, end, or at a specified position in the list by adjusting the relevant next and previous pointers.

Two-dimensional array in javaTalha mahmood

A 2-D array, or multi-dimensional array, is an array of arrays that represents data in rows and columns. A 2-D array can be declared and initialized in Java by specifying the number of rows and columns, with each element accessed using two indices for the row and column. Elements in a 2-D array must be of the same type, and the array can be initialized either during or after creation by assigning values to each element using its row and column indices.

The document describes a doubly linked list data structure. Each node in a doubly linked list contains pointers to both the next and previous nodes, allowing traversal in either direction. Common operations on doubly linked lists include inserting and deleting nodes at the beginning, end, or anywhere in the list. Pseudocode algorithms are provided to demonstrate how to implement these operations by updating the pointer references between nodes.

Java collections conceptkumar gaurav

This document discusses the collection framework in Java. It provides an overview of the need for collections due to limitations of arrays. It then describes the key interfaces in the collection framework - Collection, List, Set, SortedSet, NavigableSet, Queue, Map, SortedMap, and NavigableMap. For each interface, it provides a brief description of its purpose and characteristics. It explains that collections allow storing heterogeneous data types with variable sizes, unlike arrays.

Linked listeShikshak

The document discusses linked lists as an alternative to arrays for storing data in memory. Linked lists allow for easy insertion and removal of nodes anywhere in the list by using pointers to link nodes together rather than storing them in contiguous memory blocks. The key aspects of linked lists covered are the node structure containing data and a pointer to the next node, initializing an empty list, traversing the list, and common operations like insertion and deletion at different positions. Different types of linked lists are also introduced.

Data Structures - Lecture 7 [Linked List]Muhammad Hammad Waseem

- A linked list is a data structure where each node contains a data field and a pointer to the next node. - It allows dynamic size and efficient insertion/deletion compared to arrays. - A doubly linked list adds a pointer to the previous node, allowing traversal in both directions. - A circular linked list connects the last node back to the first node, making it a continuous loop. - Variations require changes to the node structure and functions like append/delete to handle the added previous/next pointers.

Java Stack Data Structure.pptxvishal choudhary

The Java Stack class implements a last-in, first-out (LIFO) data structure called a stack. It extends the Vector class and inherits its methods. Elements are added to the top of the stack using push() and removed from the top with pop(). The search() method returns the position of an element from the top, and empty() checks if the stack is empty. Common uses of stacks in Java include implementing undo/redo features and evaluating mathematical expressions.

Arrays In C++Awais Alam

The document discusses different types of arrays. An array is a collection of consecutive memory locations with the same name and data type. Arrays allow storing multiple values under a single name. The key types are one-dimensional, two-dimensional, and multi-dimensional arrays. One-dimensional arrays store elements in a linear list, while two-dimensional arrays can be visualized as a table with rows and columns. The document also covers array initialization, accessing elements, searching, sorting, and provides examples of one-dimensional and two-dimensional arrays.

Strings in JavaAbhilash Nair

This document discusses strings and string buffers in Java. It defines strings as sequences of characters that are class objects implemented using the String and StringBuffer classes. It provides examples of declaring, initializing, concatenating and using various methods like length(), charAt() etc. on strings. The document also introduces the StringBuffer class for mutable strings and lists some common StringBuffer functions.

single linked listSathasivam Rangasamy

This document discusses the implementation of a single linked list data structure. It describes the nodes that make up a linked list, which have an info field to store data and a next field pointing to the next node. The document outlines different ways to represent linked lists, including static arrays and dynamic pointers. It also provides algorithms for common linked list operations like traversing, inserting, and deleting nodes from the beginning, end, or a specified position within the list.

Relational databases store data in tables with rows and columns to model relationships. SQLite is an embedded SQL database commonly used in applications. SQL commands like SELECT, INSERT, UPDATE, and DELETE are used to query and modify data across related tables using integer primary keys and foreign keys. Complex data relationships can be modeled through one-to-many, many-to-one, and many-to-many connections between tables joined by common attributes.

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.
