I am making good progress using Enthuware's test simulation software (first test was a 52%, second 81%, third 72%). However, I don't seem to get any of the answers they have here in this code segment. Fortunately I guessed the right one, but I have no idea why the answer is what it is.
I went through it as follows: the first print statement will access Baap's h variable, and thus print "4", then b.getH(); will read Beta's getH method and give "Beta 44".
Then, similarly, bb will give b = "44" and getH will again be Beta's getH method and print "Beta 44". There was no constructor given, nor any static statements to worry about, so I figured this was the end of what should appear. I don't think the return statement in either getH method affects anything either. Thus my expected answer was:
