Converting .class file back to text

Question

Alright, I was playing around, making a TicTacToe game in Java and when I finished, compiled, made sure everything worked I tried to copy the files to another directory using the cp command. It took me a few tries to get the arguments right but I succeeded in the end. In the process, however, I did something and now my .java file is binary? Well, it starts with:

cafe babe 0000 0033 006a 0a00 1e00 3207

and then proceeds with similar things 140 lines downwards. Is there a way to revert it back to text?

You use a decompiler. (Or if you're crazy you open the [class file specification](https://docs.oracle.com/javase/specs/jvms/se7/html/jvms-4.html) and convert it by hand) — August, Nov 19 '14 at 22:59

The .java file is the source file. The .class is the java compiled file.

So there is nothing wrong with it.

Uhm, what if the .java file is the same? – Georgi D. Georgiev Nov 19 '14 at 23:00

You would still have the .java file. if you want to decompile your .class file, download the decompiler from the following link and open your .class file in the decompiler
