Why Java Remains the King of Programming Languages in 2025?

1. Write Once, Run Anywhere

Java’s famous “Write Once, Run Anywhere” feature means you can write your code on one platform and run it on another without making changes. This has been a game-changer for developers working across multiple environments.

Example:

Here’s a simple program that runs anywhere a Java Virtual Machine (JVM) is installed:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

Compile it once and run the .class file on Linux, macOS, or Windows—as long as there’s a JVM, it works!
