Editing a String in a .class file : <p><strong>Issue</strong></p>

<p>Hey. I've been developing a game and in the game, I was showing the version "1.0.13", and I quickly realized that it was completely incorrect, and it should display "1.9". I edit my code in Eclipse, and I didn't make backups for my code each version, so I couldn't just edit the String from Eclipse. I tried decompiling the .jar file for the game using a <strong>.jar decompiler</strong>. I downloaded the source code (.java files) and put it into Eclipse Neon. Upon putting the .java files in I realized a few errors appeared. I fixed them and ran the program. Many of the game's mechanics were completely broken. I realized that wasn't going to work, so I extracted the .jar with <strong>WinRAR</strong> and then tried editing the .class file manually (which was a stupid idea) using <strong>Notepad++</strong>. After using their built-in tool I quickly replaced all the "1.0.13"s with "1.9". Upon saving the code and running the .jar file a window appeared with the title "Java Virtual Machine Launcher" and the text "Error": A JNI error has occurred, please check your installation and try again". I then ran across a program named <strong>JBE (Java Bytecode Editor)</strong>. When using the program I was unsure how to edit the constant variables, and I searched for tutorials using the program and found none.</p>

<p>I just want to edit a single String and I've spent hours of research, and I can't even find a solution. If you know how to solve this situation, please comment. Thanks in advance.</p>
