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.
