兄弟 你那个几辆车完全可以使用for循环来写啊 我没有使用封装、动态什么的 然后直接写的代码 有些地方你可一参考一下
package com.noahcode; import java.util.Scanner; public class Main { static Scanner sc = new Scanner(System.in); static int money; static int people; static int thing; static String zPeople=""; static String zThing=""; public static void Menu() { int isZu = 0; do { System.out.println("您是否要租车：1是 0否"); isZu = sc.nextInt(); if (isZu == 1) { 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 容量"); System.out.println("1. 奥迪A4 500元/天 载人：4人"); System.out.println("2. 马自达6 400元/天 载人：4人"); System.out.println("3. 皮卡雪6 450元/天 载人：4人 载货2吨"); System.out.println("4. 金龙 800元/天 载人：20人"); System.out.println("5. 松花江 400元/天 载货：4吨"); System.out.println("6. 依维柯 1000元/天 载货：20吨"); System.out.println("请输入您要组汽车的数量："); } else if (isZu == 0) { System.exit(0); } else { System.out.println("您输入的信息有问题，请重新输入！"); } } while (isZu!=0&&isZu!=1); } public static void sumCarMoney(int n) { switch (n) { case 1: money += 500; zPeople += "奥迪A4 "; people += 4; break; case 2: money += 400; zPeople += "马自达6 "; people += 4; break; case 3: money += 450; zPeople += "皮卡雪6 "; zThing += "皮卡雪6 "; people += 4; thing += 2; break; case 4: money += 800; zPeople += "金龙 "; people += 20; break; case 5: money += 400; zThing += "松花江 "; thing += 4; break; case 6: money += 1000; zThing += "依维柯 "; thing += 20; break; } } public static void main(String[] args) { System.out.println("欢迎使用答答租车系统"); Menu(); int count = sc.nextInt(); for (int i = 1; i <= count; i++) { System.out.println("请输入第" + i + "辆车的序号"); int xh = sc.nextInt(); sumCarMoney(xh); } System.out.println("请输入租车天数："); int day = sc.nextInt(); money *= day; System.out.println("您的账单："); System.out.println("***可载人的车有：\n" + zPeople + "共载人：" + people+"人"); System.out.println("***载货的车有：\n" + zThing + "共载货:" + thing+"吨"); System.out.println("***租车总价格：" + money + "元"); } } -

封装使用的是pravite,父类变量基本租金，车名，载货载人可以用接口，
