二、代碼實現：
(1)基礎版(控制臺調試)：
car類：
package com.xiaoyao.car;
import java.util.List;
public class Car{
private int id;//租車序號
private int typeId;//租車分類下的序號
private String name;//租車名字
private double price;//租車單價
private int personLoad;//載客量；
private double goodsLoad;//載貨量；
private List carList;
public int getId() {
