Can we overload main method in java?

Yes. But the main method with String args[] is called when you call the program (java OverLoadMain) Try to understand by using this simple example .

public class OverLoadMain{

         public static void main(String[] args){

                 System.out.println("Inside main method");

         }

         public static void main(String args[],String arg){

                 System.out.println("Inside overloaded method");

         }

}
