最佳答案代码如下:
public class ElevatorModel implenent ElevatorModelListener{
ElevatorShaft elevatorShaft;//电梯车箱
Floor firstFloor;
Floor secondFloor;
public void addPerson(Person person);
//实现ElevatorModelListener接口的所有方法
}
public abstract class Location{
String locationName;//可能占据的三个位置firstFloor; secondFloor;elevator中的其中一个位置。
public Button getButton();
public Door getDoor();
}
public class Floor extends Location{
public Floor(String firstFloor,String secondFloor);
public Button getButton();//具体实现
public Door getDoor();//具体实现
public ElevatorShaft getElevatorShaft();
}
public class Door implenent ElevatorMoveListener{
boolean open;//门是开的关的
public void openDoor();//开门
public viod clossDoor();//关门
}
public class Button implenent ElevatorMoveListener{
boolean pressed;
public void pressButton();//按下按钮
public void resetButton();//释放按钮
public void elevatorArrived();//电梯到来
}
public class ElevatorShaft{//电梯乘箱
Elevator elevator;//电梯
Button firstFloorButton,secondFloorButton;//出发层的按钮和到达层的按钮 Door firstFloorDoor,secondFloorDoor;//出发的门和到达的门
Light firstFloorLight,secondFloorLight;//灯
//监听器
DoorListener doorListener;
ButtonListener buttonListener;
LightListener ligthListener;
BellListener bellListener;
ElevatorMoveListener elevatorMoveListener;
Set set;
}
public class Light implenent ElevatorMoveListener{
boolean lightOn;//代表灯的状态,亮或灭
public void turnOnLight();
public void turnOffLight();
public void elevatorDeparted();//具体实现
public void elevatorArrived();//具体实现
}
public class Bell implenent ElevatorMoveListener{
public void ringBell();
public void elevatorDeparted();//具体实现
public void elevatorArrived();//具体实现
}
public class Elevator extends Location implenets
ButtonListener,DoorListener,BellListener,Runable
{//电梯乘箱
boolean moving;
boolean summoned;//描述Elevator是在移动还是已经补召唤
Floor currentFloor;//当前正在提供服务的Floor
Floor destinationFloor ; //代表将要到达的Floor
Button elevatorButton;
Door elevatorDoor;
Bell bell;
public void run();// 实现
public void requestElevator();//请求Elevator并产生排队请求。 }
public class Person extends Thread{
Location类对象(或是位于Floor上,或是出处在Elevator中); int ID;
boolean moving;
public void run();//具体实现
public void enterAndRideElevator();
}
//TV类
public class Tv {
public void open(){
System.out.println("打开电视机");
}
public void close(){
System.out.println("关闭电视机");
}
public void search(int x){
System.out.println("您搜索到的是"+x+"号频道");
}
public void ctrlVol(String s){
int vol=10;
if(s.equals("+"))
vol++;
if(s.equals("-"))
vol--;
System.out.println("当前音量为"+vol);
}
public void changeChannel(int x){
if( x 29 )
System.out.println("没有该频道");
else
System.out.println("当前"+x+"号频道");
}
public void changeChannel(String s){
int x=0;
if(s.equals("+"))
x++;
if(s.equals("-"))
x--;
System.out.println("当前"+x+"号频道");
}
}
//Controller遥控器类
public class Controller{
public void openTv(Tv tv){
tv.open();
}
public void closeTv(Tv tv){
tv.close();
}
public void searchTv(Tv tv){
int x=(int)(Math.random()*30);
tv.search(x);
}
public void ctrlTvVol(Tv tv){
tv.ctrlVol("+");
}
public void changeTvChannel(Tv tv){
tv.changeChannel("+");
tv.changeChannel(23);
}
}
我的思路:
1.定义一个开关的接口(ISWitcher),用于设定开关的功能
2.定义开关类实现开关接口的功能
3.定义电器类,所有电器的父类
4.对电灯,投影仪,风扇等电器进行定义
5.进行测试

String course=s.next();
sort(course);

String student=s.next();
String course=s.next();
get(student,course);
}else if(comm.equals("EXIT")){
break;
}else{
System.out.println("命令格式不正确,请重新输入!");
}
