You are much more likely to get answers to your question, if you do a few things to make it as easy as possible for someone to help you.
For example, you could have posted exactly what you got from your javap -c command.
Further, you should carefully explain what part you don't understand. Do you not understand what the command is supposed to do? do you not understand one specific line of the output? do you not understand ANY of the output?
few folks are going to take the time to copy your code, save it, compile it, then de-compile it, just to see if they can try to help.
So my suggesting is to simply make life as easy as possible for the folks who may want to help you.
