Java OOPs Concepts - Class in Java with Syntax, Examples & Key Points Java OOPs Concepts Java OOPs (Object-Oriented Programming) Concepts Class Object Inheritance Polymorphism Abstraction Encapsulation 1. Class in Java A class in Java is a blueprint or template for creating objects. It defines fields (variables) and methods that represent the properties and behaviors of the object. Think of a class like a house blueprint — it defines the design (rooms, doors, windows), but the actual house is the object built from that blueprint. Syntax of a Class class ClassName { // Fields (variables) dataType variableName; // Methods (functions) returnType methodName(parameters) { // method body } } Example – Creating and Using a Class // Defining a class class Car { // Fields (Properties) ...

Chapter 7: Object-Oriented Programming (OOP) in Java Chapter 7: Object-Oriented Programming (OOP) in Java Java is a powerful object-oriented programming language. It emphasizes designing programs using real-world entities like objects and classes. OOP helps create modular, maintainable, reusable, and scalable software systems. 🔹 Four Main Principles of OOP Encapsulation Inheritance Polymorphism Abstraction 🛡️ 1. Encapsulation in Java Encapsulation is the concept of wrapping data (variables) and methods (code) into a single unit called a class. It helps hide the internal implementation of the object from the outside world. Example: class Person { private String name; private int age; public void setName(String name) { this.name = name; } public String getName() { return name; } } Benefits: Data hiding, code maintainability, security, and flexibility. 🧬 2.
