Plugin download, installation and configuration in Eclipse can refer to my other article: MyEclipse anti-compile class file
The following highlights how to use Jad to decompile
1. In the DOS window, to the directory where class is located, run >jad Db.class directly, and the Db.jad file will be generated in that directory. Run >jad-sjava Db.class, the Db.java file will be generated in this directory
2. Using the Eclipse Workbench:
1) Add the class directory to the project: (This step many documents are not written to, took me a lot of time, direct file-open file, select. class file is not open)
1.1) Project--〉 Properties--〉java buildpath--〉add class folder (e.g. a)--〉ok
1.2) A--〉import--〉general-->file System-->browse-->ok
2) Double-click the class file, the Java file appears, the compilation is successful.
The "Class file viewer" of the Eclipse Jad Decompile cannot handle the given input error resolution
