Object-Oriented Programming in Java
Hello! Just passing by real quickly.
Here's a Notion page I created a while back during my college Java course, dedicated to the concept of Object-Oriented Programming in Java.
I made it so simple and fun to read , hope it helps someone out there
Happy coding!

Exploring Java's Built-in Data Structures: A Beginner's Guide
Introduction:
Java, a versatile and widely used programming language, offers a rich set of built-in data structures that form the backbone of many applications. Understanding these data structures is fundamental for any Java developer, as they provide efficient ways to organise and manipulate data. In this beginner's guide, we'll delve into some of Java's core data structures, exploring their features, usage, and best practices.
Arrays: The Foundation
Arrays are one of the simplest and most fundamental data structures in Java. They represent a fixed-size collection of elements of the same type. Declaring an array in Java is straightforward:
This line of code creates an array of integers with a length of 5. Arrays in Java are zero-indexed, meaning the first element is accessed at index 0, the second at index 1, and so on. You can access and modify elements using square brackets notation:
Arrays are efficient for random access but have a fixed size, which cannot be changed dynamically. Java provides other data structures like ArrayList and LinkedList to overcome this limitation. To kickstart your programming career, consider enrolling in Java Training In Chennai for comprehensive learning and skill development.
ArrayList: Dynamic Arrays
A component of Java's Collection Framework, ArrayList offers dynamic arrays that can enlarge or contract in size as needed. Unlike arrays, ArrayLists can hold elements of different types and automatically resize themselves.
ArrayLists offer efficient methods for adding, removing, and accessing elements. They also provide features like sorting and searching, making them versatile for various applications. However, ArrayLists may incur performance overhead due to resizing operations when they reach capacity.
LinkedList: Linked Data Structure
LinkedList is another data structure provided by Java's Collection Framework. In contrast to arrays, elements are stored in linked lists as nodes, each of which has a reference to the node after it in the sequence. Especially in the centre of the list, this structure makes insertion and deletion operations efficient.
LinkedLists excel in scenarios where frequent insertions and deletions are required, but they may have higher memory overhead than arrays due to the additional memory needed for storing references.
HashMap: Key-Value Pairs
HashMap is a data structure that stores key-value pairs and quickly retrieves values based on their keys. It uses a hashing technique to store and retrieve elements efficiently, making it ideal for scenarios where quick access to data is crucial.
HashMaps offer constant-time performance for basic operations like insertion, deletion, and lookup, assuming a good hash function and proper handling of collisions. However, they do not maintain the order of elements.
HashSet: Unordered Collection Of Unique Elements
HashSet implements the Set interface in Java, representing an unordered collection of unique elements. It uses a hashing technique similar to HashMap to achieve fast insertion, deletion, and lookup operations.
HashSet ensures that each element is unique by internally checking for duplicates before adding them. While HashSet does not maintain the insertion order, it provides constant-time performance for basic operations.
Stack And Queue: Linear Data Structures
Java also implements two essential linear data structures: Stack and Queue.
- The latest In, First Out (LIFO) concept is adhered to by Stack, meaning that the latest piece added is also the first to be withdrawn.
- The First In, First Out (FIFO) principle is adhered to by queues, meaning that the first element added is also the first to be deleted.
These data structures find applications in various scenarios, such as expression evaluation, reversing sequences, and managing tasks in computer algorithms.
Best Practices And Considerations
While Java's built-in data structures offer powerful capabilities, it's essential to understand their strengths, weaknesses, and best practices for efficient usage:
- Choose the right data structure based on your application's requirements. Consider factors like the frequency of insertion, deletion, retrieval operations, memory usage, and performance constraints.
- Understand the time complexity of operations for each data structure. For example, ArrayList provides faster random access but slower insertion and deletion than LinkedList.
- Be mindful of synchronisation if dealing with multi-threaded applications. Java provides synchronised versions of some data structures in the `java.util.concurrent` package.
- Utilise generics to ensure type safety and reduce the risk of runtime errors when working with collections.
-Consider using wrapper classes like `Collections.unmodifiableList()` or `Collections.synchronizedList()` for immutable or thread-safe collections, respectively.
- If you're looking for the Best Software Training Institute in Chennai, look no further than our renowned institution, where expertise meets excellence.
Conclusion
Java's built-in data structures form the backbone of many applications, providing efficient ways to organise, manipulate, and access data. From simple arrays to sophisticated HashMaps and LinkedLists, Java offers a versatile toolkit for developers to tackle various programming challenges. By understanding these data structures' features, usage, and best practices, beginners can lay a solid foundation for building robust and scalable Java applications. So, dive into Java's world of data structures and unlock the full potential of your programming endeavours.

Making a compiler
Every programmer out there, new or experienced longs for a chance to create their own programming language and compiler. I am no exception. Months ago I decided to fork an old project on github and develop it in my image. The project was a golang-like unfinished compiler, so I dug in and made changes. I changed the language to resemble a subset of rust, go and ocaml. I plan to add a LLVM backend inspired by the tre golang compiler. I will continue working on it until it kinda works. I still have a lot to do. check out the project on the link below. If you want to contribute submit a pull request.

HomeFuture of JavaScript
Future of JavaScript in 2023? How can we master in JavaScript?
What is JavaScript ?
JavaScript is one of the most popular programming language in this modern era and has become the foundational part in Website of Web Development. It is basically a scripting language that helps a website Designer (Web Developer) to build interactive website for users. Along with CSS and HTML, the programming language can be used to develop dynamic websites, mobile apps, and even desktop applications. JavaScript language is run on the client side of website or within the browser of the computers.
What is JavaScript used for?
JavaScript for an explanation of how to utilize JavaScript on Wikipedia. Along with HTML and CSS, JavaScript (/ˈdʒɑːvəskrɪpt /), often frequently abbreviated as JS, is a programming language and a fundamental component of the Web. For webpage behavior, JavaScript is used on the client side by 99 percent of websites.
