4. View bytecode files through jclasslib
jclasslib is not only a bytecode reader but also contains a class library that allows developers to read, modify, and write Java Class files and bytecodes.
Since the mac installation of jclasslib requires jdk1.6, it is more troublesome. I directly install the jclasslib plug-in through intellij idea;
After installing the plugin, restart intellij idea, and open a java file in idea. At this time, there will be a menu of show bytecode in jclasslib on the View menu.
