Quick Scoop

public static void main(String[] args) is the entry point of a Java program: it is the method the JVM looks for and runs first when you start a standalone app.

What each part means

  • public : the JVM can access it from outside the class.
  • static : the JVM can call it without creating an object of the class first.
  • void : it returns nothing.
  • main : this is the special method name the JVM recognizes as the startup method.
  • String[] args : this lets the program receive command-line arguments.

In simple words

Think of it like the front door of your Java program: when you run the file, execution begins here, and then your code can call other methods from there.

Tiny example

java

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

If you want, I can also explain why the method must be public and static in an even simpler beginner-friendly way.
