I am using jdk1.2.2 and when this is ran, I get an output of 1. I thought the method that was chosen was based on the actual object? Could this result be because a B method made the call, it's method was chosen?

hi
the basic thing is that in method g() u r calling a private method f(). Remember that private methods are not overriden. thus class C method f() is not called.
if u change the B.f() method to coderanch, protected, or default u will get the result that u expect.
if u have problems do tell me.
