JD stands for ' Java Decompiler '. It is a standalone graphical utility that displays Java source codes of.class files. DJ Java Decompiler is Windows XP, Windows 2003, Windows Vista, Windows 7, Windows 8, 8.1 and 10 decompiler and disassembler for Java that reconstructs the original source code from the compiled binary CLASS files (for example Java applets).
