菜鸟从第一季看到这里 研究了半天 我也来交个作业

我只写了两个class 一个data数据class  一个入口class 通过逻辑实现调用赋值 并组合输出 代码如下 希望老师指教：

CarAllData类

public class CarAllData {

public String carName;

public int carRent;

public int carManVolume = 0;

public int carGoodsVolume = 0;

public void checkCar(int checkNum) {

if (checkNum == 1) {

this.carName = "奥迪A4";

this.carRent = 500;

this.carManVolume = 4;

}

if (checkNum == 2) {

this.carName = "马自达6";

this.carRent = 400;

this.carManVolume = 4;

}

if (checkNum == 3) {

this.carName = "皮卡雪6";

this.carRent = 450;

this.carManVolume = 4;

this.carGoodsVolume = 2;

}

if (checkNum == 4) {

this.carName = "金龙";

this.carRent = 800;

this.carManVolume = 20;

}

if (checkNum == 5) {

this.carName = "松花江";

this.carRent = 400;

this.carGoodsVolume = 4;

}

if (checkNum == 6) {

this.carName = "依维柯";

this.carRent = 1000;

this.carGoodsVolume = 20;

}

}

}

main类

import java.util.Scanner;

public class mainCar {

public static void main(String[] args) {

int rightNum = 0;

int rightRentDay = 0;

String[] carNameArray = new String[6];

int carRentCount = 0;

int carManVolumeCount = 0;

int carGoodsVolumeCount = 0;

int scannerCount = 0;

int[] scannerNum = { 0, 0, 0, 0, 0, 0, 0 };

Scanner input = new Scanner(System.in);

for (int j = 1; (j <= carNameArray.length && rightNum != -1); j++) {

CarAllData checkCar = new CarAllData();

for (int i = 0; i <= 10; i++) {

System.out.println("请输入您要租用的第 " + j + " 辆车的序号，结束选车请输入0：");

System.out.println("当前可租的车辆有：\n 1.奥迪A4  2.马自达6  3.皮卡雪6  4.金龙   5.松花江   6.依维柯");

String num = input.next();

if (i == 10) {

System.out.println("频繁输入错误 系统结束！");

rightNum = -1;

break;

}

try {

rightNum = Integer.parseInt(num);

} catch (Exception e) {

System.out.println("输入有误 请重新输入！");

continue;

}

if (rightNum < 0 || rightNum > 6) {

System.out.println("输入有误 请重新输入！");

continue;

}

if (rightNum != 0) {

System.out.println("车辆选择重复 请重新输入！");

rightNum = -2;

break;

}

}

if (rightNum == -2) {

continue;

}

}

break;

}

if (rightNum != 0 && rightNum != -1) {

checkCar.checkCar(rightNum);

carNameArray[j - 1] = checkCar.carName;

System.out.println("第 " + j + " 辆车选择成功，车辆为：" + checkCar.carName);

scannerCount++;

} else if (rightNum != -1) {

System.out.println("结束选车！");

break;

}

carRentCount += checkCar.carRent;

carManVolumeCount += checkCar.carManVolume;

carGoodsVolumeCount += checkCar.carGoodsVolume;

scannerNum[j] = rightNum;

}

for (int i = 0; (scannerCount > 0 && i < 100 && rightNum != -1); i++) {

System.out.println("请输入租用天数，停止租车请输入0：");

String num2 = input.next();

if (i == 10) {

System.out.println("频繁输入错误 系统结束！");

rightNum = -1;

break;

}

try {

rightRentDay = Integer.parseInt(num2);

} catch (Exception e) {

System.out.println("租期输入有误 请重新输入！");

continue;

}

if (rightRentDay < 0 || rightRentDay > 100) {

System.out.println("租期输入有误 请重新输入！");

continue;

}

if (rightRentDay == 0) {

scannerCount = 0;

}

break;

}

if (scannerCount > 0 && rightNum != -1) {

System.out.print("租车成功！\n··您选择的车辆为：");

for (int s = 0; s < scannerCount; s++) {

System.out.print(carNameArray[s] + "  ");

}

System.out.println();

if (carManVolumeCount != 0) {

System.out.println("··合计可载人：" + carManVolumeCount + "人 ");

}

if (carGoodsVolumeCount != 0) {

System.out.println("··合计可载货：" + carGoodsVolumeCount + "吨 ");

}

System.out.println("··租期为：" + rightRentDay + "天   合计租金为：" + carRentCount * rightRentDay + "元");

}

if (scannerCount == 0 && rightNum != -1) {

System.out.println("租车结束，您停止了租车！");

}

}

}

设计了一定的交互式  我发现自己编写过程中总有新的想法冒出来 于是改了又改  耽误了很久才最终完成 测试过没有漏洞 可能还有我不知道的漏洞和优化空间 

交作业 以上！
