Java is easy to decompile.
If you use a decompiler, the program which others made can be seen freely.
I think that it becomes the study of JAVA. However, the person who made will worsen mind.

What do you think about it?May I use it,or not?

Reference:
DJ JAVA DECOMPILER

But what about obfuscated codes!? you'll have problem with them.
anyway the program seems to be good!

I am using DJ JAVA DECOMPILER.If it refers to the keyword "decompiler", in Google,it will come out to the top.Therefore I found it out without any difficulties.
I learned JAVA with it very much.For example,hou to use constructor practically,how to make classes efficiently.Thanks to it,I am no longer a beginner.
I hear obfuscated codes can also decompile with it,but difficult to read.
(I've never tried this.)
When you use it,only what you have to be careful is not to disclosed to the author of a program.

There are so many better ways to learn Java than this... Do you know about the Sun Certified Java Programmer exam? Buy a book on it, study and take the exam. This is the way to learn.
