constant expression required

UPdate to below question. See the bug report on sunsite. So if this is correct, how
does one create a shorthand reference to a long class name?

Some more changes?

got javac message "constant expression required" for

---file
public class A {
A() {
cmd = new CommandCodes();
}

.... code

switch(int) {
case cmd.typeID: ... code;
}

--- file
public final class CommandCodes {
public final static int typeID = 1;
}

Seems this is as constant as it gets. What's with the new release 1.3?

Nushi

in the switch 'case' has to get value during compilation
thats why you get this error.

place in your code some final variables for the number you know you can get if there are only few of them.

and this will solve the problem

so why not

public final cmd = new CommandCodes();

vpadma

Your code should be

switch(CommandCodes.int) {
case cmd.typeID: ... code;
}

'int' is not a final in the scope of just the class A since int is defined to be a constant in its inner class.

Thanks for such a detail. Interesting that you mention interface... it died on me too in 1.3.
