This article introduces the relevant knowledge of "what are the advantages of java facade mode". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Reduce the interdependence of the system. If you do not use elevation mode, external access goes directly into the subsystem.

This is a strong coupling relationship, which is unacceptable to the system design. The output of the facade mode solves this problem very well, and all the dependencies are dependent on the facade object and have nothing to do with the subsystem.

2. Improve the flexibility. With less dependence, flexibility naturally increases.

3. Improve the security. If you want to access the business of the subsystem, open the logic, and the methods that are not open on the front cannot be accessed.

Example

Package com.sl.demo.facade;/** * computer (facade role) * @ author pengkun * * / public class Computer {/ / contains subsystem private CPU cpu;private GraphicsCard graphicsCard;private Memory memory;public Computer () {super (); this.cpu = new CPU (); this.graphicsCard = new GraphicsCard (); this.memory = new Memory ();} / turn on public void start () {System.out.println ("computer is on.") ; cpu.start (); graphicsCard.start (); memory.start ();} / close public void stop () {System.out.println ("the computer is turned off.") ; cpu.stop (); graphicsCard.stop (); memory.stop ();}} what are the advantages of java facade mode? thank you for reading.
