two main methods in a single program?

[ambikasd]

Hi,

Please tell me whether we can have two main methods in a single java program?

public class Main {
   private double main= 54.42;
   public Main() { }
   public static void main(String[] args) {
      Main main= new Main();
      main.main();
      main.main(42);
      main("can");
   }
   private void main() { System.out.print("yes "); }
   private void main(int i) { System.out.print("you "); }
   private static void main(String s) { System.out.println(s); }
}
 

kind regards,

Blech. That just looks awful.

1.) Why would you want 2 main functions? Are you trying to implement multithreading or something?

2.) Would you even consider that a main function: private static void main(String s) { System.out.println(s); } ? You are just overloading the main function, nothing more. The difference between a real main function and that overloaded imposter is: the program points and knows to point at the real main function. ... Am I making sense?

3.) That was really cute though.

To answer the poster's question. If you mean a method where the program starts, how can a program start at 2 different places? My answer would be no.

Huh? overloaded methods have nothing to do with multiple thread.

2.) Would you even consider that a main function: private static void main(String s) { System.out.println(s); } ? You are just overloading the main function, nothing more.

Nope, but the OP wasn't making sense either ;-)

3.) That was really cute though.

I know ;-)

Yup, and my terrible example just shows that. The question didn't make sense.
Of course different classes can all have a static void main(String[] args) method.

That Sir, is in the eye of the beholder ;-)

Sorry, I was refering to the first poster's question, not your crazy program. To me, it sounds like he wants to run 2 programs (threads) with 1 code.

Yup, and my terrible example just shows that. The question didn't make sense.

Right, but you can only run 1 at a time.
