Java Decompiler

The “Java Decompiler project” aims to develop tools in order to decompile and analyze Java 5 “byte code” and the later versions.

JD-GUI 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 and fields.

JD-Eclipse is a plug-in for the Eclipse platform. It allows you to display all the Java sources during your debugging process, even if you do not have them all.

JD-Core is a library that reconstructs Java source code from one or more “.class” files. JD-Core may be used to recover lost source code and explore the source of Java runtime libraries. New features of Java 5, such as annotations, generics or type “enum”, are supported. JD-GUI and JD-Eclipse include JD-Core library.

JD-Core, JD-GUI & JD-Eclipse are open source projects released under the GPLv3 License.

• JD-Core and JD-GUI are written in Java.
• JD-Core works with most current compilers including the following:
  • JDK 1.1.8, JDK 1.3.1, JDK 1.4.2, JDK 1.5.0, JDK 1.6.0, JDK 1.7.0, JDK 1.8.0, JDK 9.0.1, JDK 10.0.2

JD-GUI for Mac 2021 full offline installer setup for Mac

Software development and computer programming are rewarding professions, but they can be challenging too. In most cases, successful projects won’t be developed unless special 3rd party software is used to assist.

JD-GUI Java Decompiler for Mac is one of these 3rd party programs which can assist you. It lets you inspect your written coding and provide a controlled environment for decompiling your own applications.

The portability of the program meansyou don’t need to install it on a computer. Meanwhile, you can still benefit from all the features of the program. When you first receive the archive of the software, simply unpack it and then double click the executable file to launch the program.

Since it is portable, your macOS registry will not receive any new entries, and no new folders or files will be created on your computer unless you give permission. This is possible because no installation takes place. The software can be run right from an external hard drive or USB flash drive.

Interface is Simple

The interface design of the software is simple and easy to comprehend. There are no fancy menus or animations to deal with. All the menus are designed in a minimalistic style with plainly laid out toolbars and buttons.

Just because the interface isn’t attractive, it doesn’t mean the features of the program aren’t attractive. If you develop JAVA applications, then this program is a powerful decompiler and code analyzer for them. Sometimes simple is good, especially if you’re a newbie.

Efficient Project Management

The program primarily handles JAVA coding, mostly documents in JAR or CLASS format. But you can also use it for files in LOG or TXT formats too. Even ZIP archive files are supported as well.

On the main screen, the section on the left gives you a tree view option. This makes it easier to browse through the various documents and projects that you have. Just choose the class in which you’d like to review.

Search Option Available

If you need to inspect certain pieces of coding, you can use the application’s search function for that. Some of the elements you can search for are the string constants, fields, constructors, methods, and types. Use search operators like “?” or “*” to find any character or string in the coding that you want.

Reliable and Trustworthy Program

Good java program decompilers and code analyzers are difficult to find. Fortunately, you don’t need to look any further because JD-GUI for macOS is the best. It has an easy to use layout, which is simple for any novice to understand. You can use a thumb drive to run the program too. Between its project management efficiency and search functionality, this is one of the best Java code programs on the market.

Note: This is a free program if you’re not using it for commercial purposes.

8 Best Java Decompilers in 2021

What is Java Decompiler ?

Java decompiler converts .class file into java source code. In other words, decompiler converts bytecode into readable .java format.You can use java decompiler to look into the code of predefined java classes like HashMap, HashSet , ArrayList etc. You can find out how Sun/Oracle java developers wrote the java classes which are currently used by billion of devices in the world.

Java source code from which the .class file has been generated will not exactly match the java source code generated from the java decompiler. But most of the code will be same.

After installing java, you can find the predefined java classes in the rt.jar inside JRE folder. Unzip rt.jar and all the predefined java classes will be present in the bytecode(.class) format. By using java decompiler, I have written the articles how HashMap works in java, how HashSet works in java. So let’s find out best java decompilers which I have used and now I am recommending it to you.

Best Java Decompilers

JDProject is one of the most frequently used java decompiler offline.It is developed to decompile java 5 or later versions(as of now till java8). It is available for Windows, Mac OS and Linux. It is a best decompiler for eclipse and intellij too as it provides plugin for each platform. JD-Eclipse is a plug-in for the Eclipse platform while JD-Intellij is a plug-in for Intellij IDEA.
You can download JDProject java decompiler from here

Procyon 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 does well with enum declarations, annotations and java 8 lambdas and method references. You can find the wiki here comparing Original code, Procyon decompiler code and JD decompiler code. Although wiki above makes Procyon looks good, but I still prefer JDProject over Procyon. Procyon is relatively new and still work in progress.

If you are a Windows user, then Cavaj is a good option as a decompiler. It is simple to use and decompiles nearly any java class file. The main drawback of Cavaj is that it lacks syntax highlighting.
Also, it is not available for Mac or Linux OS. In short, it is a freeware standalone windows application which converts bytecode(.class) files to java source code.

DJ Java Decompiler is yet another standalone windows application. It is available for Windows XP, Windows 2003, Windows Vista, Windows 7, Windows 8, 8.1 and 10. You don’t need to have the JVM (Java Virtual Machine) or any other java JDK installed. The main advantage of DJ Java Decompiler is that you can decompile more than one java class file at one time. DJ Decompiler enables users to users to save, print, edit and compile the generated java code.

JBVD stands for java bytecode viewer and decompiler. It is based on the javassist open source library. It is only available for Windows OS. JBVD requires java to be installed on your device to work.

AndroChef is also a windows based java decompiler application. With AndroChef Java Decompiler you can decompile apk., dex, jar and java class-files. It’s simple and easy. AndroidChef supports Windows XP, Windows 2003, Windows Vista, Windows 7, Windows 8, 8.1 and 10. AndroChef successfully decompiles java6, java 7 and java 8 .jar and .class files.

CFR stands for Class File Reader. It is completely written in java 6. It supports latest features of java8 like lambdas while decompiling. You do not need to worry if you are using java 8. The only drawback of this decompiler is that it is not an open source program. Although, it has a command line tool which is ideal in making the decompiling process efficient and faster.

Fernflower is an analytical decompiler for java. It is used to decompile class, zip and jar file extensions. It is still under development.
