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！

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这个是我写的测试类，写的不好，请见谅
