用来降低类类之间的耦合,使用中介者模式只需关心和Mediator类的关系,具体类类之间的关系及调度交给Mediator就行
//中介者类
public interface Mediator {
public void createMediator();
public void workAll();
}
public class MyMediator implements Mediator {
private User user1;
private User user2;
public User getUser1() {
return user1;
}
public User getUser2() {
return user2;
}
@Override
public void createMediator() {
user1 = new User1(this);
user2 = new User2(this);
}
@Override
public void workAll() {
user1.work();
user2.work();
}
}
//user类
public abstract class User {
private Mediator mediator;
public Mediator getMediator(){
return mediator;
}
public User(Mediator mediator) {
this.mediator = mediator;
}
public abstract void work();
}
//user1 类
public class User1 extends User {
public User1(Mediator mediator){
super(mediator);
}
@Override
public void work() {
System.out.println("user1 exe!");
}
}
//user2 类
public class User2 extends User {
public User2(Mediator mediator){
super(mediator);
}
@Override
public void work() {
System.out.println("user2 exe!");
}
}
//使用
public class Test {
public static void main(String[] args) {
Mediator mediator = new MyMediator();
mediator.createMediator();
mediator.workAll();
}
}
