How i can edit .class files?

How I can edit .class files ? Because i want to translate to polish. Can you tell me what editor can do that ?

 

Decompile with a <what do you think is the program called? Yeah, it's a decompiler!>, then open it with your favorite java editor/IDE, where you can edit it, then compile it into .class files and if necessary, export into a .jar.
The decompiler i use to have a look at source codes is JD:

I can copy and open .class files but i can't edit ;/

 

Even if you can decompile class files you will have a very frustrating time trying to do what you are saying. Unless you know Java and are familiar with building plugins this will be a daunting task.

My advise is to contact the developers of the plugin/plugins you need in another language and offer to translate the messages. This would be 50 times easier than decompiling a class file and recompiling it into a working plugin.

 

CTRL+Alt+S, then unzip the src.zip

 

what plugin you are trying to translate exactly?

 

Factions

Grab Faction's source, translate the needed files, and then compile the plugin again... For sure you'll need to learn it.
(you have to read everything before Bukkit Javadocs and then Deploying your plugin)
