要求实现的功能有：

1.展示所有可租车辆

2.选择车型，租车量

3.显示租车清单，包括：总载货量，总载客量，总金额等；

4、车辆类型

客车：只能载客

货车：只能载货

皮卡：既能载人，有能载货

Java代码：

    import java.util.Scanner;
    
    class Vehicle{
    	String name;
    	int num;
    	int passenger_num;

    		passenger_num = a;
    		goods_num = b;
    		if(passenger_num == 0) {
    			System.out.print("只能载货"+"                  ");
    		}
    		else if(goods_num == 0) {
    			System.out.print("只能载客"+"                  ");
    		}
    		else{
    			System.out.print("既能载人有能载货"+"   ");
    		}
