    ackage java.util;

    import java.util.Scanner;

    public class car {

       String carName;

       int carNumber;

       int carMonney;

       public void carr(){

      System.out.println("1号车");

       }

     public void pipk(){

    System.out.println("2号车");

     

     }

     public static void  mian(String[] ages){

    car net=new car();

    @SuppressWarnings("resource")

    Scanner sc=new Scanner(System.in);

    System.out.print("欢迎使用租车系统");

    System.out.println("回复1:继续租车   回复 2 退出系统");

    int x=sc.nextInt();

    if(x==1){

    net.carr();

    }else {

    net.pipk();

    }

    为什么我这里键盘输入1之后没反应!求解!


    一缕阳光19...

    因为是Carr()是void类,是无返回值类型

    我的思路是

    1.定义了一个Car抽象类
    2.定义了一个载客接口和一个载货接口
    3.定义具体类轿车继承Car实现载客接口
    4.定义具体类客车继承Car实现载客接口
    5.定义具体类轻卡继承Car实现载货接口
    6.定义具体类重卡继承Car实现载货接口
    7.定义具体类皮卡继承Car实现载货接口和载客接口
    8.定义一个测试类实现哒哒租车系统
