Why “final static int” can be used as a switch's case constant but not “final static ”

Question

Why is this int switch valid:

public class Foo {
    private final static int ONE = 1;
    private final static int TWO = 2;

    public static void main(String         


        

Answer 1

Or simply use a if-elseif case :

private final static int ONE = 1;
private final static int TWO = 2;

public static void main(String[] args) {
    int value = 1;

    if(value.equals(ONE)){

    }
    else if(value.equals(ONE)){

    }

}
