java jar package decompilation

Since the previous Sina account cannot be used, I am lucky to find the page of the original account, write an article on java decompilation, and copy it here, this account will continue to write some development and sharing.

To decompile java, such software exists, and jd_gui is used to decompile java.
jd_gui.exe, download address: http://www.cr173.com/soft/5606.html
Operation: Drag the jar package into the tool panel to load it to view, save it as .zip to view or reference it to MyEclipse.

    But jd_gui.exe fails to fully display the complete code. For example, the method of using a class of a jar package during development can be used. If we press Alt+/, there is such a method, but jd_gui.exe is not compiled.

    Here you can configure the jad plug-in of MyEclipse/Eclipse. The jad effect can see the methods that are not displayed. Here you will see some information about the JVM. It may be that the JVM has performed further analysis. I guess it is like this~

If you use MyEclipse2014, there may be a problem with MyEclipse2014 not responding

Tips : The decompiled files can be copied to NotePad for easy analysis, or copied to MyEclipse/Eclipse development tools for analysis.
