Understand MVC in java?

The full name of MVC is model view controller, which is the abbreviation of Model-View-Controller. It is a model of software design. It uses the method of separating business logic, data and interface display to organize code, and gathers business logic into one component. There is no need to rewrite business logic while improving and personalizing the interface and user interaction. MVC is specially developed to map traditional input, processing and output functions into a logical graphical user interface structure.

Simply understanding the role of MVC is to separate the front end and the back end.
