Hey I got a problem that I'm hoping someone can help me with. I'm still fairly new to Java, but this problem I feel is definitely for you advance people who I hope will kindly point me in the right direction. I'm an Intern and working for someone on creating a website for them and they asked me to create a counter for them and they aren't giving me much time so I figure the best route would be to decompile the class file to go from there. Well in decompiling it didn't do it correctly and I'm really hoping someone can help me out so to get to the point does anyone know what the heck is "0xb2d05e00L" below is all of the source code that hopefully will help you to better understand it. Thanks in advance for the help.

Matt

0x is a prefix for all numbers in Hexadecimal format (base 16)
0 is a prefix for all numbers in octal format (base 8)
all other numbers are in standard decimal format.

So... 0xb2d05e00 is really 3,000,000,000 (I'm guessing they wrote it in hex so they wouldn't goof and miss a zero).

The suffix "L" means that the number should be interpretted as a long rather than an int.

0xb2d05e00L (hex) just happens to be equal to 3000000000L (decimal), and it looks to me like a way to provide a few leading zeroes to the counter's display

You might want to consider a few things:

a) It is probably illegal for you to decompile some arbitrary .class file.
b) Regardless of the licence for use of the software, you might be implicating the company that you are doing your internship for, in a lawsuit for breach of copyright.
c) The cost of producing a counter by someone other than yourself is neglible when compared to cost of any lawsuit - especially one such as the possible one as a result of your actions.
d) What you are doing is unethical and considered very unprofessional - an internship often leads to a job - in this case, I would recommend against someone who actively engages in unethical behaviour (I have successfully recommended all interns that I have worked with in the past).
e) Why don't you simply learn how to do it properly anyway? If you don't know how to learn, you will have serious problems once you step into the industry (no, we don't make counters all day ).

Well said Tony.

If you don't have enough time you may not be the person for the job which is very valuable information when evaluating an intern.

You're not ready for the real world, trying to cheat yourself into a job by stealing someone else's code will not help you in the long run in that you won't be able to do your job properly.
It can also lead to severe legal trouble for you and the company (if the company gets sued they'll almost certainly fire you on the spot and sue you in turn, it could get you in prison too).

Ok thank you for the help and the lecture. For those of you who lectured me I didn't mean to give the impression I was stealing code from somebody. The class file I got this from is from the same company that my company is working on redesigning their website and who owns the copyright to it and I'm merely just editing it with everyone's approval. Surely if I actually did stole this code from someone I wouldn't be stupid enough to say that I did.
