How to Decompile JAR files and View Source Code of Java Programs

Typically, The Contents of any JAR file can be viewed by Extracting the JAR file with the Help of Tools like WinZIP or WinRAR . Once You have successfully extracted the contents of the JAR file . you will get a lot of Files with file extension " .class " and these class files are not in Human Readable Format. So, to Overcome this problem and to view the original JAVA source code hidden inside these class files stored inside the JAR file container ,we use a tool called JD-GUI . JD stands for "Java Decompiler" . It is a standalone graphical utility that displays Java source codes of “ .class ” files. You can browse the reconstructed source code with the JD-GUI for instant access to methods
