    Default Re: Static method

    In that specific code you will get a compile time error because that number is too big to fit in an int.

    However is that number was smaller and would fit into an int it would pick the int method over the other two because Java will always pick the method signature nearest to what you are passing in.

    Thanks,

    But there is also double value argument is there right?...so when i passing the value more than int value,it should automatically call the double value argument method right?...

    Unfortunately, no. If you called it like this:

    test(102420000000[b].[/b]);

    It will figure out that you want a double and call the appropriate method.

    hey wait a second..

    i tried this one in the main method

    	public static void main(String[] args)
    	{
    		test(102420000000L);// i put an L , so it supposed to be "LONG" integer ryt?
    	}


    but it refered to the method signature that has 'double' argument

    it displayed .

    Double


    and how am i supposed to refer at the method with 'short' argument?
    what kind of number should i pass to a method 'test' to refer it to the method with 'shor' parameters?
    what number format?
    it always display 'int' instead of short.



    why?
