我只寫了兩個class 一個data數(shù)據(jù)class? 一個入口class 通過邏輯實現(xiàn)調(diào)用賦值 并組合輸出 代碼如下 希望老師指教：

CarAllData類

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 = "奧迪A4";

this.carRent = 500;

this.carManVolume = 4;

}

if (checkNum == 2) {

this.carName = "馬自達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 = "金龍";

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 = "依維柯";

this.carRent = 1000;

this.carGoodsVolume = 20;

}

}

}

main類

import java.util.Scanner;

public class mainCar {

public static void main(String[] args) {

int rightNum = 0;

System.out.println("請輸入您要租用的第 " + j + " 輛車的序號，結(jié)束選車請輸入0：");

System.out.println("當前可租的車輛有：\n 1.奧迪A4? 2.馬自達6? 3.皮卡雪6? 4.金龍? ?5.松花江? ?6.依維柯");

String num = input.next();

if (i == 10) {

System.out.println("頻繁輸入錯誤 系統(tǒng)結(jié)束！");

rightNum = -1;

try {

continue;

System.out.println("租期輸入有誤 請重新輸入！");

continue;

}

if (rightRentDay == 0) {

scannerCount = 0;

}

break;

}

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

System.out.print("租車成功！\n··您選擇的車輛為：");

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

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

}

System.out.println();

if (carManVolumeCount != 0) {

System.out.println("··合計可載人：" + carManVolumeCount + "人 ");

}

if (carGoodsVolumeCount != 0) {

System.out.println("··合計可載貨：" + carGoodsVolumeCount + "噸 ");

}

System.out.println("··租期為：" + rightRentDay + "天? ?合計租金為：" + carRentCount * rightRentDay + "元");

}

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

System.out.println("租車結(jié)束，您停止了租車！");

}

}

}

設(shè)計了一定的交互式? 我發(fā)現(xiàn)自己編寫過程中總有新的想法冒出來 于是改了又改? 耽誤了很久才最終完成 測試過沒有漏洞 可能還有我不知道的漏洞和優(yōu)化空間?

交作業(yè) 以上！
