% character in switch statement

[rainman33]

I've looked online and in my textbook, but can't find any explanations for what "wildcards" do in controlling expression parentheses. I have the following code:

1 	switch ( value % 2 )
2 	{
3 		case 0:
4 			outputJTextField.setText( "Even Integer" );
5
6 		case 1:
7 			outputJTextField.setText( "Odd Integer" );
8 			break;
9
10 	} // end switch

I can't figure out what the "%" does in my switch controlling expression. Can anyone please provide me with a list of wildcard characters that are recognized in Java switches, and their uses?

Thanks.

% is not a wild card character. It is an operator. Google "% operator Java" and find out what it does.

Perhaps understanding how the switch statement works can be of help to you.
