外观模式

//外观模式
public class Facade {

    private SubSystem1 subSystem1 = new SubSystem1();
    private SubSystem2 subSystem2 = new SubSystem2();
    private SubSystem3 subSystem3 = new SubSystem3();

    public void method(){
        subSystem1.methhod1();
        subSystem2.methhod2();
        subSystem3.methhod3();
    }
}
//子系统一
public class SubSystem1 {

    public void methhod1(){
        System.out.println("调用子系统一");
    }

}
//子系统二
public class SubSystem2 {

    public void methhod2(){
        System.out.println("调用子系统二");
    }

}
//子系统三
public class SubSystem3 {

    public void methhod3(){
        System.out.println("调用子系统三");
    }

}
//测试一下！
public class test {

    public static void main(String[] args) {
        Facade facade = new Facade();
        facade.method();
    }

}
