Java Decompiler Download The Static

Although sometimes when reverse engineering something you dont always have access to binaries.

Outdated, unsupported and does not decompile correctly Java 5 and later.

Java comes with something that lets you see JVM byte code ( javap ).

Use Procyon, the CFR decompiler or Krakatau (Python) instead.

Its under active development and supports many features of the latest versions of Java.

Also actively developed with support for the latest Java features.

From my testing it was roughly on par with Procyon, but still nice to have something different.

I did have to use the -skip command-line flag so it wouldnt stop on errors.

Actively developed, and interestingly enough its written in Python.

JD-GUI is also available as an Eclipse plugin, which didnt work for me at all.

Doesnt seem to be open source and development seems sporadic.

At least it has the advantage of still being recently maintained.

You could just open a JAR file and browse through the code as if.

You will get the actual Java code, but sometimes the code will have been obfuscated so methods are named by one letter or number or a random mix of letters and numbers.

Its a great tool, but unfortunately hasnt been updated for a while and does not handle Java 1.5 classes very well.

I have not seen any tools that will properly handle 1.5 classes.

Works great (for Linux, at least) On Ubuntu 11.10 I had to download the static one for whatever reason.

Decompilation involves transforming the bytecode into Java source, meaning that a lot of low level information is lost, and if youre wondering about compiler optimization, this is probably the very information youre interested in.

Unlike Javap, this works even on highly pathological classes, so you can see what obfuscation tools are doing to your classes as well.

It can also do decompilation, though I wouldnt recommend it.

At least it has Open Java source code and been able to decompile my.class properly.

It allows you to display all the Java sources during your debugging process, even if you do not have them all.

Maybe you should add more details and also your answer only comply with question title not with content of question.
