This article mainly introduces how to realize the facade pattern in java design pattern. In daily operation, I believe many people have doubts about how to realize the facade pattern in java design pattern. Xiaobian consulted all kinds of materials and sorted out simple and easy to use operation methods. I hope to answer your doubts about how to realize the facade pattern in java design pattern. Next, please follow the small series to learn together!

Facade pattern, also known as facade pattern, is mainly used to hide the complexity of the system and provide an interface for the client to access the system.

We know that the operation of TV series is very simple, but few people understand the design and principle inside. This is because the design of TV series applies the facade mode.

TV series at least needs the following functions: signal input, audio processing, Media Processing Service, signal output, etc

/** * RF Signal Input */public class SignalIn { //} * Audio/Video Signal Output public class SignalOut { * Audio Processing public class AudioProcess { * Media Processing Service public class VideoProcess {

The principle behind this is something that only a few professionals understand. In order for ordinary people to use TV series, we need to provide an easy-to-use interface for TV series

/** * TV */public interface Television { /** * power switch */ public void powerSwitch(); * switch channels public void channelSwitch(); * adjust the volume public void volumeAdjust();}

For most people, it was enough to switch the TV on and off, switch channels, and adjust the volume. He did not need to know the other principles to use the TV.

If we buy TCL TV for a day, its internal design may be very complicated, as long as the above interface is implemented, we can use it.

/** * TCL Television */public class TCLTelevision implements Television{ private SignalIn in; private AudioProcess audioProcess; private VideoProcess videoProcess; private SignalOut out; @Override public void powerSwitch() { } public void channelSwitch() { public void volumeAdjust() {}

This is the power of the facade pattern. Hide complex logic and expose easy interfaces.

At this point, the study of "how to realize the facade pattern in java design pattern" is over, hoping to solve everyone's doubts. Theory and practice can better match to help you learn, go and try it! If you want to continue learning more relevant knowledge, please continue to pay attention to the website, Xiaobian will continue to strive to bring more practical articles for everyone!
