Java 简易租车系统

###Car 抽象类

//Car 类
public abstract class Car {
	private int price;//车的租金
	private String name;//车的名字
	private int passengerLoad;//载客人数
	private double goodsLoad;//载客数量
	public int getPrice() {
		return price;
	}
	public void setPrice(int price) {
		this.price = price;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getPassengerLoad() {
		return passengerLoad;
	}
	public void setPassengerLoad(int passengerLoad) {
		this.passengerLoad = passengerLoad;
	}
	public double getGoodsLoad() {
		return goodsLoad;
	}
	public void setGoodsLoad(double goodsLoad) {
		this.goodsLoad = goodsLoad;
	}
	
}

###客车

//只载人的KeCar类
public class KeCar extends Car {
	public KeCar(String name, int price, int passengerLoad) {
		// TODO Auto-generated constructor stub
		this.setName(name);
		this.setPrice(price);
		this.setPassengerLoad(passengerLoad);
		
		
	}

	@Override
	public String toString() {
		return this.getName()+"----"+this.getPrice()+"元/天----载客"+this.getPassengerLoad()+"人";
	}
}

货车

//货车Truck类
public class Truck extends Car {
	public Truck(String name, int price, int goodsLoad) {
		// TODO Auto-generated constructor stub
		this.setName(name);
		this.setPrice(price);
		this.setPassengerLoad(goodsLoad);
		
		
	}

	@Override
	public String toString() {
		return this.getName()+"----"+this.getPrice()+"元/天----载货"+this.getGoodsLoad()+"屯";
	}
}

###即载人又载货

//载人和货的BothCarry类
public class BothCarry extends Car {
	public BothCarry(String name, int price,int passengerLoad, double goodsLoad) {
		// TODO Auto-generated constructor stub
		this.setName(name);
		this.setPrice(price);
		this.setPassengerLoad(passengerLoad);
		this.setGoodsLoad(goodsLoad);
		
		
	}

	@Override
	public String toString() {
		return this.getName()+"----"+this.getPrice()+"元/天"+this.getPassengerLoad()+"人/货物"+this.getGoodsLoad()+"屯";
	}
}

###测试类

import java.util.Scanner;


public class Test {
	public static void main(String[] args) {
		System.out.println("****欢迎使用**租车系统****");
		System.out.println("*******租车请按 （1）       退出请按 （0）*******");
		Scanner input = new Scanner(System.in);
		int num = input.nextInt();
		Car[] cars={
				new KeCar("大众",300,5),
				new KeCar("宝马",800,4),
				new KeCar("宝骏巴士",800,45),
				new Truck("东风Rl",1000,10),
				new Truck("依维柯S",1500,25),
				new BothCarry("皮卡雪Z",600,2,5),
				new BothCarry("皮卡雪Z",600,2,15)
		};
		if (num != 1) {
			System.out.println("****欢迎下次光临****");
			System.exit(0);
		}else{
			for (int i = 1; i <= cars.length; i++) {
				System.out.println("序号"+i+"----"+cars[i-1]);
			}
		}
		System.out.println("请输入预定数量");
		int carNum = input.nextInt();
		int priceSum = 0;//价格总量
		int passengerLoadSum = 0;//载客总量
		double goodsLoadSum = 0;//载货总量
		for (int i = 1; i <= carNum; i++) {
			System.out.println("请输入第"+i+"辆要预定车辆的序号");
			int index = input.nextInt();
			priceSum=priceSum+cars[index-1].getPrice();
			passengerLoadSum=passengerLoadSum+cars[index-1].getPassengerLoad();
			goodsLoadSum=goodsLoadSum+cars[index-1].getGoodsLoad();
		}
		System.out.println("一共需要"+priceSum+"元/天"+" "+"共载货量："+goodsLoadSum+"吨 "+"共载客量："+ passengerLoadSum+"人");
		System.out.println("***********谢谢惠顾！*************");
	}
}
