1 Introduction No matter which programming language, has provided three kinds of basic program flow control statements, respectively is the order, the choice and the cycle, these three kinds of program structure can solve every single thread problem in the life, each kind of algorithm foundation also consists of these three kinds of program flow structure. The sequential Process Control statement means that the program is executed from the first line of code in the Main method. If there is a ca

This article continues with an example to gain an in-depth understanding of the implementation of bytecode for dynamic change methods of method components. By the previous article, you know that Classvisitor's Visitmethod () method can return an instance of Methodvisitor. Then we can also basically know that with classvisitor change class members, methodvisistor if need to change method members, inject logic, can also inherit Methodvisitor, To write a
