Java Programming Introduction

Java is a general-purpose, object-oriented programming language created by James Gosling at Sun Microsystems and released in 1995. Its core design goal was portability — Java code compiles to bytecode that runs on the Java Virtual Machine (JVM), summed up in the phrase “write once, run anywhere.” Java is statically typed, strictly object-oriented, and includes automatic memory management through garbage collection. It’s widely used for enterprise backends, Android apps, and large-scale systems.

Why Learn Java?

  • Platform-independent thanks to the JVM.
  • Strong typing catches many errors at compile time.
  • Backbone of Android development and enterprise software.
  • Built-in garbage collection simplifies memory management.

Structure of a Java Program

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
ComponentPurpose
public class MainEvery Java file’s main content lives inside a class
public static void main(String[] args)Entry point every Java program starts from
System.out.println()Prints output to the console
This is a starter page — more Java topics (OOP, collections, exception handling) will be added here as modules, the same way the C Language section is structured.
