JD GUI: The Ultimate Java Decompiler for Developers - Free Download


If you are a Java developer, you may have encountered situations where you need to analyze or modify some Java class files that you don't have the source code for. For example, you may want to debug a third-party library, reverse engineer an obfuscated code, or patch a legacy application. In such cases, you need a tool that can decompile the class files and display the Java source code in a readable and editable format.

One of the most popular and powerful tools for this purpose is JD-GUI, which stands for Java Decompiler Graphical User Interface. JD-GUI is a standalone application that can decompile Java class files and JAR files and show you the reconstructed source code in a graphical interface. You can browse the source code with ease, using features such as tree view, tabs, hyperlinks, search, and syntax highlighting. You can also save the source code as a ZIP file or a directory for further use.

Use the command line with Java

If you are an advanced user who wants to customize the launch options of JD-GUI, you can also use the command line with Java. For example, you can specify the memory allocation, the look and feel, or the classpath for extensions. To do this, open a terminal or a command prompt and type something like this:

java -jar -Xmx512m -classpath jd-gui-x.y.z.jar;my-extension.jar org.jd.gui.App

This command will launch JD-GUI with 512 MB of memory, using the Nimbus look and feel, and including a custom extension called my-extension.jar. You can modify these options according to your needs. For more information on the available options, you can check the file in the GitHub repository.

How to use JD-GUI

Now that you have launched JD-GUI, you can start using it to decompile Java class files or JAR files and view their source code. In this section, we will provide a step-by-step guide on how to open, browse, and save Java source codes with JD-GUI.

How to open a file with JD-GUI

To open a file with JD-GUI, you have two options: use the menu or drag and drop. To use the menu, click on File and then Open File.... A dialog box will appear where you can select the class or JAR file that you want to open. Alternatively, you can drag and drop the file from your file explorer to the JD-GUI window. Either way, JD-GUI will decompile the file and display its source code in a new tab.

How to browse the source code with JD-GUI

To browse the source code with JD-GUI, you have several features that make it easy and convenient. Here are some of them:

  • Tree view: On the left side of the window, you will see a tree view that shows the structure of the class or JAR file that you opened. You can expand or collapse the nodes to see the packages, classes, methods, fields, and constants. You can also right-click on any node to access some options such as copy, search, or go to declaration.

  • Tabs: On the top of the window, you will see tabs that show the names of the files that you opened. You can switch between tabs by clicking on them or using keyboard shortcuts. You can also close tabs by clicking on the x button or using keyboard shortcuts. You can also right-click on any tab to access some options such as close, close others, close all, or reopen closed tab.

  • Hyperlinks: In the source code, you will see some words that are highlighted in blue and underlined. These are hyperlinks that allow you to jump to the declaration or definition of a class, method, field, or constant. You can click on any hyperlink to go to the corresponding location in the source code. You can also use the Back and Forward buttons on the toolbar to navigate your browsing history.

  • Search: If you want to find a specific word or phrase in the source code, you can use the search feature of JD-GUI. You can access it by clicking on Edit and then Find..., or by using keyboard shortcuts. A dialog box will appear where you can enter your search query and some options such as case sensitive, whole word, or regular expression. You can also use the Find Next and Find Previous buttons on the toolbar to move between the search results.

Syntax highlighting: To make the source code more readable and understandable, JD-GUI uses syntax highlighting to color different elements of the code such as keywords, comments, strings, numbers, and annotations. You
