Java

📄️ Introduction to Java

Hey, everyone! In this guide, we'll explore the fundamentals of Java programming language.

📄️ Datatypes in Java

Hey there! In this guide, we'll explore the different data types available in Java. Understanding data types is crucial for writing efficient and clear Java code. Let's dive in!

📄️ Variables in Java

Hey, everyone! In this guide, we'll explore the concept of variables in Java. Variables are essential in programming, allowing you to store and manipulate data dynamically. Let's dive in!

Hey there! In this guide, we'll explore operators in Java. Operators are symbols that instruct the compiler to perform specific operations on variables or values. Java supports a variety of operators, including arithmetic, relational, logical, bitwise, and more. Let's dive in!

📄️ Code Style Guide

Guidelines for writing clean, readable, and beginner-friendly Java DSA examples.

📄️ Decision Making in Java

Hey there! In this guide, we'll explore decision-making in Java. Decision-making structures allow you to execute different blocks of code based on certain conditions. Let's dive in!

📄️ Multithread in Java

What is a Thread?

📄️ Loops In Java

Hey there! In this guide, we'll explore loops in Java. Loops are used to execute a block of code repeatedly based on specific conditions. Let's dive in!

📄️ Strings In Java

Hello! In this guide, we'll explore how to work with strings in Java. Strings are a crucial part of Java programming as they allow you to manipulate and process text easily. Let's dive in!

📄️ Fast I/O (BufferedReader)

Learn how to prevent TLE (Time Limit Exceeded) errors by using BufferedReader and PrintWriter in Java.

📄️ Classes

Overview

📄️ Objects

Overview

📄️ Inheritance in Java

Hey there! In this guide, we'll explore the concept of inheritance in Java. Inheritance allows one class to inherit fields and methods from another class, promoting code reusability and organization. Let's dive in!

📄️ Interfaces in Java

Hey there! In this guide, we'll explore the concept of interfaces in Java. Interfaces are used to define abstract methods that classes can implement, allowing for multiple inheritance and flexibility in designing systems. Let's get started!

📄️ Memory management

Memory management is a critical aspect of the Java Virtual Machine (JVM). The JVM is responsible for managing the memory resources of a Java application, including allocation, garbage collection, and deallocation of objects. The JVM's memory management model is designed to optimize performance, scalability, and reliability.

📄️ Generics in Java

Generics in Java allow you to write more flexible, reusable, and type-safe code. With generics, you can define classes, interfaces, and methods with type parameters, so you can create code that works with any type of data, while still maintaining type safety.

📄️ functional programming

Introduction to functional programming in Java — immutability, pure functions, lambda expressions, and the Streams API overview.

📄️ I/O and Serialization in Java

In Java, reading from and writing to external sources (like files, network connections, or the console) is handled via I/O Streams. An I/O Stream represents an input source or an output destination. And Serialization helps you to store the state of an object into a byte stream.
