Which one of these is a proper definition of a class TestClass that cannot be sub-classed? (choose one)
final class TestClass { }
abstract class TestClass { }
native class TestClass { }
static class TestClass { }
private class TestClass { }

Answer is 1.
My question is: does 'subclassing' a class mean exactly the same as extending it?

Thanks.

Yes, that is correct. Subclassing is another term that means the same as extending.

what about private class?

What happened when you tried it out?

ok so the outer class cannot have private modifier
