That should fail to identify subclasses and I speculate the OP tries
to achieve just that but I'm not really sure because of his approach
with static method(s).
I'm not sure what you mean by "fail to identify subclasses."
Perhaps you meant nested classes? Even so, it will produce a
name like "org.borg.assimilate.Foo$Bar".
I've meant the case where the getType() is defined in a base class but
invoked from a subclass context which subclass doesn't redefine the method:
public abstract class Armor {
public static String getType() {
return ...;
}
}
public class BackArmor extends Armor {
public void foo() {
...
String type = getType();
...
}
}
The same would happen if getType() is non-static and is not overridden
in the subclass.
You have shown why it's a bad idea to invoke static methods as if from a
subclass. Static methods belong to the class in which they're defined, not to
any subclass. Unless hidden, static methods are accessible from subclasses as
if they belonged to the subclass, but it's an illusion. Really they only
belong to the class in which they appear. Static methods cannot be
overridden, only hidden, by subclasses, so there's no workaround for subclass
invocation other than invoking them via the subclass.
