switch() don't work with constant

[jarek]

class Class_A {
    public static final int TT_EOL = 10;
}

class TestSwitch {
    public static void main(String args[]) {
        Class_A obj = new Class_A();

        int i = 10;
        switch (i) {
            case Class_A.TT_EOL : //but expression 'obj.TT_EOL' don't work
                System.out.println("i = " + i);
                break;
        }
    }
}

any ideas?

You need to specify a compile time constant expression. (See JLS 15.28). TypeName.Identifier is OK if it refers to a constant variable, but the compiler is not going to go investigating obj to see that it's a constant 10.

obj.TT_EOL is wrong anyway ;)

Thank a lot! :)
