Java Basics every beginner should learn to build a strong foundation: 1. Hello World & Setup Install JDK and an IDE (like IntelliJ or Eclipse) Write your first program: public class HelloWorld 2. Data Types & Variables Primitive types: int, double, char, boolean Non-primitive types: String, Arrays, Objects Type casting (implicit & explicit) 3. Operators Arithmetic: + - * / % Comparison: == != > < >= <= Logical: && || ! 4. Control Flow If, else if, else Switch-case Loops: for, while, do-while break and continue 5. Functions (Methods) Syntax: public static returnType methodName(params) Method overloading Return types & parameter passing 6. Object-Oriented Programming (OOP) Classes & Objects this keyword Constructors (default & parameterized) 7. OOP Concepts Encapsulation (private variables + getters/setters) Inheritance (extends keyword) Polymorphism (method overriding) Abstraction (abstract classes & interfaces) 8. Arrays & ArrayList Declaring and iterating arrays ArrayList methods: add, remove, get, size Multidimensional arrays 9. Exception Handling Try-catch-finally blocks throw and throws Custom exceptions 10. Basic Input/Output Scanner class for user input System.out.println() for output Free Java Resources: https://whatsapp.com/channel/0029VamdH5mHAdNMHMSBwg1s ENJOY LEARNING 👍👍

Polymorphism in Java 📍 Polymorphism allows a single interface to be used for different types of actions. 📍 It is of two types: Method Overloading (Compile-time Polymorphism) Method Overriding (Runtime Polymorphism) Method Overloading (Same method name, different parameters) class MathOperations { int add(int a, int b) { return a + b; } double add(double a, double b) { return a + b; } } Method Overriding (Same method in parent and child class) class Animal { void makeSound() { System.out.println("Animal makes a sound"); } } class Dog extends Animal { void makeSound() { System.out.println("Dog barks"); } } 🔗 More Java Resources: https://whatsapp.com/channel/0029VamdH5mHAdNMHMSBwg1s
