汽车租赁管理系统（java）–隔壁小河

代码亲测有效，各位大佬就不用看了吧，小白看过来呀
一个简单的汽车租赁问题，分为四个类：父类CarHire,子类Bus和Vehicle,再加一个业务类（Service）.测试类我可能写的有点复杂------QQ1942295707;欢迎交流

import java.util.Scanner;

abstract class CarHire {
	String number;//车牌号
	String brand;//品牌
	int rent;//租金
	CarHire(){}
	CarHire(String number, String brand, int rent){
		this.number = number;
		this.brand = brand;
		this.rent = rent;
	}
	public String getBrand() {
		return brand;
	}
	
	public int getRent() {
		return rent;
	}
	
	public String getNumber() {
		return number;
	}
	public abstract int calRent(int days);//计算租金的抽象函数
}


class Bus extends CarHire{
	int setCount;//客车座位数
	public Bus() {}
	public Bus(int setCount, String number, String brand, int rent) {
		super(number, brand, rent);
		this.setCount = setCount;
	}
	public int calRent(int days) {
		int price;
		if (setCount <= 16)
			price = days*800;
		else

	}

	
}
