Java

Java is a high-level, object-oriented, and platform-independent programming language developed by Sun Microsystems (now owned by Oracle Corporation) in 1995.

🔑 Key Features of Java:

Simple: Easy to learn if you know the basics of programming.

Object-Oriented: Everything in Java is an “object” that makes the code more modular and reusable.

Platform-Independent: Java programs are compiled into bytecode, which runs on the Java Virtual Machine (JVM). So, “write once, run anywhere”.

Secure: Java has built-in security features to develop virus-free and tamper-free applications.

Robust: Strong memory management and exception handling.

Multithreaded: Can perform many tasks at once using threads.

Portable: Java code can run on any device that has JVM.

🔧 Java Program Example:

public class HelloWorld {

public static void main(String[] args) {

System.out.println(“Hello, World!”);

}

}

⚙️ Java Compilation and Execution:
