Without further ado, when you suffer from no source code, you can decompile the class to get the source code through the well-known jad command. Of course, for technical tycoons, studying the source code is not to solve the problem, but to some kind of 'faith'-gold rushing to superior code architecture. I wonder if everyone feels the same as me?Įspecially when you encounter problems during debugging, do you have the urge and need to understand the internal implementation mechanism and implementation principles of third-party jars in order to solve problems and develop efficiently? For Java developers, the lack of source code may make you unbearable.
