Room类3个私有属性:房间编号，房间类型，房间状态

Initroom类对房间进行初始化和更改房间信息

package no4;
    import java.util.Scanner;
    public class Hotel{
    	public static void main(String[] args) {
    		Scanner in = new Scanner(System.in);
    		System.out.println("酒店管理系统");
    		Initroom s = new Initroom();
    		System.out.println("输入房间编号");
    		while (true){
    			s.print();
    			String temp = in.nextLine();
    			s.change(temp);
    		}
    	}
    }
    class Room{
    	//3个属性房间编号，房间类型，房间状态
    	private String id;
    	private String type;
    	private boolean sta;
    	Room(){
    	}
    	Room(String id, String type, boolean sta){
    		this.id = id;
    		this.type = type;
    		this.sta = sta;
    	}
    	public String getid(){//取出编号
    		return this.id;
    	}
    	public boolean getsta(){//取出当前房间状态
    		return this.sta;
    	}
    	public String gettype(){
    		return this.type;
    	}
    	public void setsta(boolean sta){//存入当前状态
    		this.sta = sta;
    	}
    	public String toString(){
    		return "[" +this.id+ "]" +" "+"["+this.type+"]"+" "+"["+(this.sta==false ? "空闲":"已入住")+"]";
    	}
    }
    class Initroom{
    	Room[][] arr = new Room[4][4];//创建对象数组保存房间信息
    	Initroom(){//构造初始化所有房间
    		for (int i=1; i<arr.length; i++){
    			for (int j=1; j<arr[i].length; j++){
    				String str;
    				if (i == 1){
    					str = "标准间";
    				}
    				else if(i==2){
    					str = "双人间";
    				}
    				else{

    				}
    				arr[i][j] = new Room(i*100+j+"", str, false);//初始化房间
    			}
    		}
    	}
    	public void change(String id){//更改房间状态
    		for (int i=1; i<arr.length; i++){
    			for (int j=1; j<arr[i].length; j++){
    				if (arr[i][j].getid().equals(id)){
    					if (arr[i][j].getsta() == true){
    						arr[i][j].setsta(false);
    					}
    					else{
    						arr[i][j].setsta(true);
    					}
    				}
    			}
    		}
    	}
    	public void print(){
    		for (int i=1; i<arr.length; i++){
    			for (int j=1; j<arr.length; j++){
    				System.out.println(arr[i][j]);//因为重写了toString方法可以直接输出对象
    			}
    		}
    	}
    }
