我的Java之旅——答答租车系统

今天试着写了一个新的程序，叫做“答答租车系统”，是慕课网上的一个综合练习，戳我看原题。

我的代码(简单粗暴版)：

Vehicle.java

public class Vehicle {
    String name;         //车名
    int rent;            //租金
    int seatingCapacity; //载人量
    int cargoCapacity;   //载货量


    //构造方法，初始化变量
    public Vehicle(String newName, int newRent,
                   int sCapacity, int cCapacity) {
        name = newName;
        rent = newRent;
        seatingCapacity = sCapacity;
        cargoCapacity = cCapacity;
    }


    //打印可租车的类型及其价目表
    public void Display(int i) {
        System.out.print(i + "           " + name + "            " + rent + "          ");
        if (seatingCapacity != 0) {
            System.out.print("载人：" + seatingCapacity + "人" + "  ");
        }
        if (cargoCapacity != 0) {
            System.out.print("载货：" + cargoCapacity + "吨");
        }

        System.out.print("\n");
    }
}

Main.java
