A question about the main()

[Michelle Chang]

A question about the main(); Can we take var-arg as the argument of the Main()? Are these two legal as the argument of the Main()? Thanks.

    
public static void main(String...a){}
public static void main(String... a){}

There are three alternatives of main, all are equivalent:

    
public static void main(String [] a){}
public static void main(String a []){}
public static void main(String... a){}

var-arg as be used as a replacement of an array

I think, your first code is wrong, second is correct!

What's happened when you tried?

[bhanu chowdary]

The first one will not compile

[Ganesh Dhakshinamurthy]

When i tried the first one, it compiled and executed successfully. Am I missing something here?

 
public static void main(String...a){}

[Afzal Rehman]

Both codes works!
even Which i figure out after do some testing...
codes works.

Let say

 
public static void main(String[]args){}    // This works
public static void main(String..args){}    // This works


public class Test{
 public static void main(String...args){
}
public void myMain(Integer...args){ } // This works 

}
   

Which my conclusion it's works with var-args and Arrays without spaces ... in any method
but It will not compile with primitive and Object etc.

It's something to do with Arrays but if someone put some Green Light on it it would be helpful to
understand the reason....
