How to call the main function in Java?

In Java, the main method serves as the entry point of the program and can be called by following these steps:

1. Create a class that includes a main method, for example:

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

1. Compile this class: execute “javac Main.java” in the command line.
2. Run this class: execute “java Main” in the command line.

This will invoke the main method and execute the code within it. If there are arguments to be passed to the main method, they can be added after the java command at runtime, for example: java Main arg1 arg2. The args parameter will contain the passed argument values.
