Non-final methods in a final class

Question

My question is pretty simple:
Does the compiler treat all the methods in a final class as being final themselves? Does adding the final keyword to methods

Answer 1

May be the compiler treats them as final.

The following prints "false":

final class FinalClass {
    public void testMethod() {}
}

Method method = FinalClass.class.getDeclaredMethod("testMethod");
int m = method.getModifiers();
System.out.println(Modifier.isFinal(m));
