这是包的名字  
这里我用了while语句和switch-case语句来提高代码的互动性  
![在这里插入图片描述][20200406224109694.png]

package Phone;
    
    import java.util.Scanner;
    
    public class phonedemo {
        
    
        public static void main(String[] args) {
        
    	//写入手机种类及配置
    	CellPhone p1 = new CellPhone("华为","6.58","5000","8+512");
    	CellPhone p2 = new CellPhone("Iphone","6.5","1000","4+256");
    	
    	//利用while循环展示手机
    	while (true){
        
    		System.out.println("-----------欢迎进入您的手机小仓库-----------");
    		System.out.println("请选择你要查看的手机");
    		System.out.println("1.华为p40pro+");
    		System.out.println("2.Iphone11pro");
    		System.out.println("3.走出仓库");
    		
    		Scanner sc = new Scanner(System.in);
    		String line = sc.nextLine();
    		//利用switch语句调用展示方法和进行功能操作的switch语句
    		switch (line) {
        
    		case "1":{
        
    			//展示方法调用
    			p1.Show();
    			System.out.println("请选择你要使用功能");
    			System.out.println("1.发短信");
    			System.out.println("2.打电话");
    			//功能的操作
    			String function = sc.nextLine();
    			switch (function){
        
    			case "1":{
        
    			    //调用sendMessage方法
    			    p1.sendMessage();
    			    break;
    			}
    			case "2":{
        
    			  //调用callPhone方法
    			    p1.callPhone();
    			    break;
    			}
    			default:
    				System.out.println("对不起您输入的信息有误，已退出手机使用");
    				break;
    			}
    			break;
    		}
    		case "2":{
        
    			//展示方法调用
    		    	p2.Show();
    		    	System.out.println("请选择你要使用功能");
    			System.out.println("1.发短信");
    			System.out.println("2.打电话");
    			String function = sc.nextLine();
    			switch (function){
        
    			case "1":{
        
    			  //调用sendMessage方法
    			    p2.sendMessage();
    			    break;
    			}
    			case "2":{
        
    			  //调用sendMessage方法
    			    p2.callPhone();
    			    break;
    			}
    			default:
    				System.out.println("您输入的信息有误，请重新输入");
    				break;
    			}
    			break;
    		}
    		case "3":{
        
    			//直接结束系统运行
    			System.out.println("已退出仓库");
    			System.exit(0);
    		}
    		default:
    			System.out.println("您输入的信息有误，请重新输入");
    			break;
    		}
    	}
    
    }
    
    
    
    }

这是手机的包

package Phone;
    
    import java.util.Scanner;
    
    public class CellPhone {
        
        //定义手机属性
        private String logo;
        private String screen;
        private String camera;
        private String memory;
    
        //无参方法
        public CellPhone() {
        
        				
        }
        //set get方法
        public CellPhone(String logo, String screen,String camera,String memory) {
        
    	    this.logo = logo;
    	    this.screen = screen;
    	    this.camera = camera;
    	    this.memory = memory;
    	}
       
        public void setlogo(String logo) {
        
            this.logo = logo;			
        }
        public String getlogo(){
        			
            return logo;			
        }
        public void setscreen(String screen) {
        
            this.screen = screen;			
        }
        public String getscreen(){
        				
            return screen;			
        }
        public void setcamera(String camera) {
        
            this.camera = camera;			
        }
        public String getcamera(){
        				
            return screen;			
        } 
        public void setmemory(String memory) {
        
            this.memory = memory;			
        }
        public String getmemory(){
        				
            return memory;			
        }
          //show展示手机信息的方法
        public void Show(){
        
            System.out.println("这是一部"+memory+"G内存，"+camera+"万像素，"+screen+"英寸的"+logo+"牌手机"); 
        }
          //构建sendMessage方法，输入信息，输入发送失败的提示
        public static void sendMessage() {
        
        	Scanner sc = new Scanner(System.in);
        	
        	System.out.println("请输入要发送的信息");
        	String message = sc.nextLine();
        	System.out.println("发送成功！");
        }
        //构建callPhone方法，输入电话号，输入无法拨打的提示
        public static void callPhone(){
        
            Scanner sc = new Scanner(System.in);
        	
        	System.out.println("请输入要拨打的电话");
        	String call = sc.nextLine();
        	System.out.println("对不起您的手机已欠费，无法拨打");
        }
          
    }

运行结果展示
