In section 4, "Class conversion with Javassist", you learned how to use the Javassist framework to convert compiler-generated Java class files and write back the modified class file. This kind of file conversion procedure is ideal for making

Source: Click to open the link The order of Java class initialization is often confusing, and now this article tries to give the JVM an explanation by experimenting with the initialization order of classes in the Java non-inheritance and inheritance
