car类:
package com.CarRentSystem; public class Vehicle { String name; int carryPerson; int carryFreight; int price; public Vehicle(String name,int carryPerson,int carryFreight,int price){ this.name = name; this.carryPerson = carryPerson; this.carryFreight = carryFreight; this.price = price; } public int rent(int days){ int rent = days * this.price; return rent; } }
主函数:
package com.CarRentSystem; import java.util.Scanner; public class Initial { public static void main(String[] args){ Vehicle[] cars = {new Vehicle("奥迪A6",4,0,500), new Vehicle("马自达6",4,0,400), new Vehicle("皮卡雪6",4,2,450), new Vehicle("金龙",20,0,800), new Vehicle("松花江",0,4,400), new Vehicle("依维柯",0,20,1000)}; Scanner input = new Scanner(System.in); System.out.println("欢迎使用喵喵租车系统!"); System.out.println("请问是否需要租车:1是,0否"); int ifRent = Integer.parseInt(input.next()); if ( ifRent == 1){ System.out.println("您可选择的租车类型及价目表:"); System.out.println("序号\t汽车名称\t\t租金\t\t\t容量"); for (int i = 0 ;i < 6;i++){ System.out.print(i + 1 + "\t"); System.out.print(cars[i].name + "\t\t" ); System.out.print(cars[i].price + "元/天\t\t"); if (cars[i].carryPerson == 0){ System.out.println("载货:" + cars[i].carryFreight + "吨"); }else if (cars[i].carryFreight == 0){ System.out.println("载人:" + cars[i].carryPerson + "人"); }else{ System.out.println("载人:" + cars[i].carryPerson + "人,载货:" + cars[i].carryFreight + "吨"); } } }else{ System.out.println("欢迎再次使用本系统!"); return ; } System.out.println("请输入需要租车的总天数:"); int days = Integer.parseInt(input.next()); System.out.println("请输入需要租车的总数量:"); int carCount = Integer.parseInt(input.next()); int allCars[] = new int[carCount]; for (int j = 1;j < carCount + 1;j++){ System.out.println("选择第" + j + "辆车的编号:"); allCars[j-1] = Integer.parseInt(input.next()); } System.out.print("您选择的车辆为:"); int allPerson = 0; int allFreight = 0; int allPrice = 0; for (int m = 0; m < carCount; m++){ int carCode = allCars[m]; System.out.print(cars[carCode].name + " "); allPerson += cars[carCode].carryPerson; allFreight += cars[carCode].carryFreight; allPrice += cars[carCode].rent(days); } System.out.println(); System.out.println("共可载人:" + allPerson + "人"); System.out.println("共可载货:" + allFreight + "吨"); System.out.println("总价格为:" + allPrice + "元"); } }
输出如下:
欢迎使用喵喵租车系统!
请问是否需要租车:1是,0否
1
您可选择的租车类型及价目表:

3 皮卡雪6 450元/天 载人:4人,载货:2吨
4 金龙 800元/天 载人:20人
5 松花江 400元/天 载货:4吨
6 依维柯 1000元/天 载货:20吨
请输入需要租车的总天数:

你没发现输出结果与序号不匹配吗?车辆序号都往后移了一位。
从49行数组后面有点懵
