Can we overload main method

Can we overload main method

Answer: Sure you could overload main method without any issues but only public static void main(String[] args) will be used when your class is launched by the JVM. For example:

package com.javahonk;

public class MainMethodTest {

    public static void main(String[] args) {
	System.out.println("main(String[] args)");
    }

    public static void main(String arg1) {
	System.out.println("main(String arg1)");
    }

    public static void main(String arg1, String arg2) {
	System.out.println("main(String arg1, String arg2)");
    }

}

 

Above will always print:

Can we overload main method

You can call the main() method yourself from code and execution point the normal overloading rules will be applied.

Note: You can use a varargs signature, as that’s equivalent from a JVM standpoint shown below:

public static void main(String… args) is equivalent to public static void main(String[] args) from Java 1.5 onward.
