What is Java?
Java is a high-level, class-based, object-oriented programming language that is designed to be platform-independent. "Write Once, Run Anywhere" (WORA) is a key principle of Java.
It's widely used for developing a broad range of applications, including:
- Enterprise Applications
- Android Mobile Apps
- Web Applications
- Desktop Applications
Key Concepts
Here's a breakdown of some fundamental Java concepts:
- Object-Oriented Programming (OOP): Java is built around OOP principles like encapsulation, inheritance, and polymorphism.
- Classes and Objects: Everything in Java is an object. Classes are blueprints for creating objects.
- Variables and Data Types: Java has various data types (int, float, String, boolean, etc.) to store different kinds of data.
- Control Flow Statements: These statements (if-else, switch, for, while) control the order of execution in your program.
