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。
项目要求截图如下：
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
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
Vehicle[] vehicles = new Vehicle[7];
vehicles[1] = new Vehicle("奥迪A4 ", 500, 4, 0);
vehicles[2] = new Vehicle("马自达6", 400, 4, 0);
vehicles[3] = new Vehicle("皮卡雪6", 450, 4, 2);
vehicles[4] = new Vehicle("金龙 ", 800, 20, 0);
vehicles[5] = new Vehicle("松花江 ", 400, 0, 4);
vehicles[6] = new Vehicle("依维柯", 1000, 0, 20);
System.out.println("欢迎使用嗒嗒租车系统！");
System.out.println("您是否需要租车？");
System.out.println("是：请输入数字1 不是：请输入数字2");
int y = 0;
if (scan.hasNextInt()) {
y = scan.nextInt();
}
//若用户输入数字1，则进入租车流程
if (y == 1) {
int i;
System.out.println("您可租车的类型及其价目表：");
System.out.println("序号" + " " + "汽车名称" + " "
+ "租金(元/天)" + " " + "容量");

}
