Decompilers

A quick guide to best java decompilers for the java developers offline usage and best online java decompilers.1. Overviewin this tutorial, We’ll learn what are the best java decompilers for the java developers and what are javaonline decompilers available for free usage.For some of the developers who do not have access to download it to the development machines, they might need the help of online decompilers.2. What is Decompiler?When the java class is compiled and then the JVM generates the .class file for that class. That means java source code is converted into the .class file which is in the form of the byte stream.Now the generated class file is not in a readable format. So, how to read the class file in java?Java Decompiler converts the byte stream data into the readable source file.Many times, you might be in the need to see the third party jars source code to debug issues.If you do not have the right decompiler tool then you can not view the .class file in java.By using Decompiler, you can view the source code for java built in api classes for String, ArrayList, HashSet and HashMap classes.All java API classes are present in the rt.jar file. This file is generated by the JDK as soon as you install java on your machine.Every java developer must have one java decompiler to become a better programmer by seeing the .class files internal code.3. Java Decompiler ToolsIf you are using only eclipse then only you need the decompiler.

Decompiler (Free, GPL)JODE decompiler and optimizer (Free, GPL)JReversePro (Free, GPL)SourceTec Java Decompiler (commercial, patch to Mocha)JavaWorld published areviewcomparing Mocha to two other early Java decompilers, DejaVu and WingDis.More information on early java decompilers can be found in theJava Decompiler HOW-TO by Alavoor Vasudevan.Where can I get Crema?Due to restrictions in the Crema license agreement, I am unable to provideit.Crema was integrated into Borland'sJBuilder product. PresumablyBorland has fixed bugs and/or added features.Several other obfuscators are available:Hashjava (shareware, no longer maintained)-->jarg optimizer and obfuscator (Free, BSD)JavaGuard (Free, GPL)Jmangle (free, source code available)Jobe (shareware, free for non-commercial use, registration includes source code, $20 personal license, $40 site license)-->Jshrink (commercial, trial version available for download)ProGuard (free, GPL)RetroGuard (commercial and noncommercial licenses available, library free under LGPL license)Smokescreen (commercial, trial version available for download)SourceGuard (commercial, based on Hashjava, trial version available for download)-->yGuard (based on LGPL Retroguard)Douglas Low has written a technical paper"Protecting Java Code via Code Obfuscation".Technical Support for Mocha and Crema...... is not available from me. Sorry. I've only just started playing withJava, and haven't even tried to use Mocha yet. But I when I heard aboutMocha I thought it could be a very cool and useful tool. Perhaps people onUsenet might be willing to offer assistance. Last updated May 20, 2007 Copyright 1996-2001, 2005, 2007 Eric Smith eric@brouhaha.com

You need to add the jd decompiler to it.But if you IntelliJ idea user, by default it comes with the inbuilt decompiler which works flawlessly.Let us see the offline java decompiler tools and choose the best one for you.3.1 JDProject Java DecompilerJDProject means java decompiler project. This works on windows, unix and mac os.JDProject is the most used java decompiler in the world by java developers because it has the support for the Eclipse IDE and offline tool as well.This one is easy to use and supports java 1.1 onwards.And also JD has syntax highlighting and also open multiple jars at the same time from the offline tool.This can easily reconstruct the java source file from the any version java .class file.Works with enums, collections, java 8 stream apis as well.Download from here.3.2 ProcyonProcyon is a java decompiler developed by Mike Strobel. Procyon decompiler handles java language enhancements from JDK 1.5 and beyond that most other decompilers don’t. Procyon really works very well with enum declarations, annotations, java 8 lambdas and method references. Compare to this, I suggest to use the JD project decompiler because Procyon is still a new one and still development is in progress.DownloadGitHub pageWikl page3.3 Neshkov – DJ Java compiler This is also another free decompiler tool.DJ decompiler is windows based and support all windows operating systems till windows 10.This is a standalone tool like the above decompilers with GUI.The main advantage of this tool is, JDK is
