you don't need to: that's a plain cheat.

I changed my mind and invalidated this kind of hack. It's too easy, and it isn't specific for this task.

I‘ve changed the byte of the Class, but I can't reload the class, could someone give me some hints

Oh, I just saw that you did do a lot of hard work in your other solution. Did you succeed in the end? Most of the code is commented out...

I think this smells like cheating (I mean, look at how much hard work the others had to go through), but you're right - it's Hack-22. All's fair in love and war. ;-)

It worked fine for me

Please, stop creating issues with no information at all.

Closing because this "issue" is, ultimately, not helpful to anyone in resolving anything in any way.

If you don't describe your question (yes, it's a question not an issue), give the input you get, the expected value shown and the actual value your code returned (sometimes along with your code posted in spoilers), nobody can help you.

What doesn't work?

You could try to solve it.
