How to decompile a .class file into .java file using DEJDecompiler?

Hi all,
I am using DeJDecompiler and working with swing applications.If I try to convert a .class file into .java file,it is converting into .jad file only.Fine but if I try to save that file into .java file,It is giving lot of errors in that program.When I went into that program the total style of the program is changed and TRY-CATCH block is not recognised by the dejdecompiler,hence If I try to include some methods in the existing .java file thus got,I could not do.Kindly help me.
If I get the .java file without error then I can process the rest of the functionality.
Thanks in advance

How to convert class files into java files??

Hey Guys,
I need a little help.
I want to know wheather we can view .class files as .java files or convert the .class to .java files.Is ther any tool or software for doing that.
Or in other words can i see the source code of any .class file..??
Plz do tell me if we can do that or any other way we can do that.
Regds,
Gokul

Sort of. A "decompiler" will take a class file and generate a source code file of source code that could be compiled to get the class file you started out with. However, it won't be the same source code that was originally used to create the class. Most notably, comments will be missing, and variable names will probably be meaningless.
And before you say "java is bad because you can decompile it", note that any language that you can execute you can theoretically decompile.
Also, you can view the raw byte codes. If you're familiar with assembly language, or better yet familar with java bytecodes and the JVM in particular, you can often find out what a particular method does just by viewing the byte codes.

Does anybody know how to convert x.class file back to a x.java file.As Dr.Clap said, that's decompiling.
Or in other terms, extract .java files from a jarfile??That isn't quite the same thing. You can decompile a .class that's in a jar, but a .class file doesn't have to be in a jar and a file in a jar isn't necessarily a .class.

Again,HOW to conver a .class file into .java one?

sorry , but Can't u send me a specific link for downloading this "Java decomplier"??
coz I found my self in something called (jad decompiler) with lots of versions and this is confusing
and Is that mean, that there's a decompiler which can convert the .class file into .java one?
and thanks alot man.....u help me always!
(I'm still begginner in java)

Just to emphasise what yawmark said...
Decompiled java code is NEVER going to be as clear as well-written original java source code. The decompiler can see what the compiled code does but not why or what it means, so the source code that the decompiler produces is going to be ugly and hard to read. Decompilers are really only useful for experienced programmers who know what to infer, how to read between the lines...
If you need help writing something, then you're better off looking at tutorials. In tutorials the code will be well-commented.

How to combine the classes from 2 jar files into 1?

Hi there
I have got 2 jar files with the same name but the classes that they contain are different. So, I want to combine those 2 files into 1. Could anyone please tell me how to add the classes in a jar file to another jar file?
Thanks for your help!

The jar utility allows you to extract files as well as put them into a jar. This is in the java docs.
You might have to hand modify the manifest file if it was hand modified in the first place. All you should have to do is copy the text from one file to another. The manifest will have the same name so you will have to extract to different dirs so it isn't overwritten.
Steps:
-Create dir1 and dir2
-Extract jar1 into dir1, Extract jar2 into dir2.
-Manually examine manifests and combine if needed.
-Copy files from one dir to another.
-Use jar tool to create new jar.

Converting class files into java source codes

Dear Friends,
It is true that conversion of class files to its java source codes is possible through some software. I want to know, is there any way to protect my java source codes from viewing or copying illegally by other persons ?
If I create JAR file from java files, can it be also convertible back to source codes ?
Avi

You can use code obfuscators in order to protect your code. And yes a jar file can also be decompiled.
