What is the appearance mode of Facade facade mode? in order to solve this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Facade facade mode (appearance mode)

Appearance pattern (Facade), which hides the complexity of the subsystem and provides the client with an interface to access the system. This type of design pattern belongs to structural pattern. Provides a unified access interface for a set of interfaces in the subsystem, which makes the subsystem easier to access or use.

Suppose there are three systems now. If the appearance mode is not used, the code is as follows: ↓↓↓

Public static void main (String [] args) {System1 system1 = new System1 (); System1 system2 = new System1 (); System1 system3 = new System1 (); system1.fun1 (); system2.fun1 (); system3.fun1 (); system1.fun2 (); system2.fun2 (); system3.fun2 (); system1.fun3 (); system2.fun3 () System3.fun3 ();}

Now that the appearance mode is used, the code structure has become clear

Public class SystemFacade {private System1 system1; private System2 system2; private System3 system3; public SystemFacade () {system1 = new System1 (); system2 = new System2 (); system3 = new System3 ();} public void fun1 () {system1.fun1 (); system2.fun1 (); system3.fun1 ();} public void fun2 () {system1.fun2 () System2.fun2 (); system3.fun3 ();} public void fun3 () {system1.fun3 (); system2.fun3 (); system3.fun3 ();}} public static void main (String [] args) {SystemFacade systemFacade = new SystemFacade (); systemFacade.fun1 (); systemFacade.fun2 (); systemFacade.fun3 () } the answer to the question about the appearance mode of Facade facade mode is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
