下面是代码，也算是自己学习的时候做的笔记：

public class MediatorPattern {    public static void main(String[] args) {        AbsColleague colleagueA = new ColleagueA();        AbsColleague colleagueB = new ColleagueB();        colleagueA.setX(400);                MediatorClass mediatorClass=new MediatorClass(colleagueA, colleagueB);        mediatorClass.setNumb();                System.out.println("colleagueB中x的值为："+colleagueB.getX());    }}class MediatorClass{         AbsColleague a,b;    public MediatorClass(AbsColleague a, AbsColleague b) {        this.a = a;        this.b = b;    }    public void setNumb() {        b.setX(a.getX()*100);    }}abstract class  AbsColleague{    protected int x;    public int getX() {        return x;    }    public void setX(int x) {        this.x = x;    }    public abstract void  setNumb(int x,MediatorClass mediator);    }class ColleagueA extends AbsColleague {    @Override    public void setNumb(int x, MediatorClass mediator) {        super.x = x;    }}class ColleagueB extends AbsColleague {    @Override    public void setNumb(int x, MediatorClass mediator) {        super.x=x;    }}

public class MediatorPattern { public static void main(String[] args) { AbsColleague colleagueA = new ColleagueA(); AbsColleague colleagueB = new ColleagueB(); colleagueA.setX(400); MediatorClass mediatorClass=new MediatorClass(colleagueA, colleagueB); mediatorClass.setNumb(); System.out.println("colleagueB中x的值为："+colleagueB.getX()); }}class MediatorClass{ AbsColleague a,b; public MediatorClass(AbsColleague a, AbsColleague b) { this.a = a; this.b = b; } public void setNumb() { b.setX(a.getX()*100); }}abstract class AbsColleague{ protected int x; public int getX() { return x; } public void setX(int x) { this.x = x; } public abstract void setNumb(int x,MediatorClass mediator); }class ColleagueA extends AbsColleague { @Override public void setNumb(int x, MediatorClass mediator) { super.x = x; }}class ColleagueB extends AbsColleague { @Override public void setNumb(int x, MediatorClass mediator) { super.x=x; }}
