Question

I am using Neatbeans 7.0 for Java programming. I have written a Switch case for selection of the program.

switch(menu)
        {
            case 1:
            {
                //stmt
            }
            default:
            {
                //stmt
                return;
            }
        }

I am getting compile time error at switch(menu)

The Error is "strings in switch are not supported in -source 1.6
  (use -source 7 or higher to enable strings in switch)

(Alt-Enter shows hints)” Can any one please help me on this.

I’m assuming here that menu is a string type, though it doesn’t really match your case statements. Allowing the use of strings in switch statements was added in Java 7.

You can either switch to Java 7 and fix the case so that it checks against a string rather that the integral 1, or convert menu to an integer and check that, such as with Integer.ParseInt(), something like:

String menu = "1";
int menuint;
try {
    menuint = Integer.ParseInt (menu);
} catch (NumberFormatException e) {
    menuint = -1;
}
switch (menuint) {
   :
