About this question
So, I am working on this class that has a few static constants:
public abstract class Foo {
...
public static final int BAR;
public static final int BAZ;
public static final int BAM;
...
}
Then, I would like a way to get a relevant string based on the constant:
public static String lookup(int constant) {
switch (constant) {
case Foo.BAR: return "bar";
case Foo.BAZ: return "baz";
case Foo.BAM: return "bam";
default: return "unknown";
}
}
However, when I compile, I get a constant expression required error on each of the 3 case labels.
I understand that the compiler needs the expression to be known at compile-time to compile a switch, but why isn't Foo.BA_ constant?
