Reverse engineering help
Hey so I have a java in an exe program. It uses java runtime. It isn't obfuscated so I can see all the source files in winrar, and I've decompiled it in jd gui, and I know what I wanna change but I don't know how to. I can't delete files in winrar (says archieve is corrupted) and I can't see the code without decompiling it. I have saved the changed file aswell as all the other files but its just a folder and I dont know how to compile it or delete the file in winrar
