Many times when we work in the company, we cannot see the source code when Eclipse refers to the jar package packaged by others, so we cannot understand the intentions of others well, so we need the help of decompilation. Well, here is the correct way to use decompilation.
1. Download net.sf.jadclipse_3.3.0.jar and put it in the plugins folder under the Eclipse folder
2. Delete the org.eclipse.update folder under the configuration folder under the Eclipse folder
3. Download jad.exe and put it in the Eclipse folder
4. Open Eclipse, click window→preferences→Java→JadClipse in the menu bar, the configuration is as shown in the figure (modify the path according to the location of your own file), the second path can be left blank
