Java入门第二季 综合练习 答答租车系统

1.定义汽车抽象类

package proje2;


public abstract class Acar {

private int num;   //序号

private String name;  //车名

private int price;   //价格

private int busload;  //载客量

private int cargoload;   //载货量

public int getNum() {

return num;

}

public void setNum(int num) {

this.num=num;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name=name;

}

public int getPrice() {

return price;

}

public void setPrice(int price) {

this.price=price;

}

public int getBusload() {

return busload;

}

public void setBusload(int busload) {

this.busload=busload;

}

public int getCargoload() {

return cargoload;

}

public void setCargoload(int cargoload) {

this.cargoload=cargoload;

}

public String toString() {

return num+" "+name+" "+price+"元/天 "+"载客量:"+busload+"人/载货量:"+cargoload;

}

}


2.定义轿车,客车,货车,皮卡车类,分别继承汽车抽象类

package proje2;


public class Car extends Acar {

public Car(int num,String name,int price,int busload) {

this.setNum(num);

this.setName(name);

this.setPrice(price);

this.setBusload(busload);

}

}


package proje2;


public class Bus extends Acar {

public Bus(int num,String name,int price,int busload) {

this.setNum(num);

this.setName(name);

this.setPrice(price);

this.setBusload(busload);

}

}


package proje2;


public class Truck extends Acar {

public Truck(int num,String name,int price,int cargoload) {

this.setNum(num);

this.setName(name);

this.setPrice(price);

this.setCargoload(cargoload);

}

}


package proje2;


public class Pickup extends Acar {

public Pickup(int num,String name,int price,int busload,int cargoload) {

this.setNum(num);

this.setName(name);

this.setPrice(price);

this.setBusload(busload);

this.setCargoload(cargoload);

}

}


3.测试类


package proje2;

import java.util.Scanner;



public class Test {


public static void main(String[] args) {

// TODO Auto-generated method stub

Acar c[] = new Acar[6];  

c[0]=new Car(1,"奥迪A4",500,4);

c[1]=new Car(2,"马自达6",400,4);

c[2]=new Pickup(3,"皮卡雪6",450,4,2);

c[3]=new Bus(4,"金龙",800,20);

c[4]=new Truck(5,"松花江",400,4);

c[5]=new Truck(6,"依维柯",1000,20);

Scanner input = new Scanner(System.in); //创建Scanner对象

System.out.println("欢迎使用答答租车系统!");

    System.out.println("你是否要租车:1是? 0否?");

int i = input.nextInt(); //获取用户输入信息并保存到变量中

while(i != 0 && i != 1) {

System.out.println("您输入的信息有误,请重试");

i = input.nextInt();

}

if(i == 0) {

System.out.println("欢迎再次光临答答租车系统!");

System.exit(0);

}else if(i == 1){

System.out.println("您可选择的租车类型及价目表:");

System.out.println("序号 车名  租金  载客/载货量");

for(int j=0;j<c.length;j++) {

System.out.println(c[j]);

}

System.out.println("请输入您想要租的汽车数量:");

int m = input.nextInt();

while( m <= 0 ) {

System.out.println("您输入的信息有误,请重试");

m = input.nextInt();

}

String[] d = new String[m];

int[] e = new int[m];

int[] f = new int[m];

int[] g = new int[m];

for(int k=0;k<m;k++) {

System.out.println("请输入第"+ (k+1) +"辆车的序号:");

int l = input.nextInt();

    while(l < 1 || l > 6) {

    System.out.println("不存在该序号的车辆,请输入数字为1-6之间的数字");

    l = input.nextInt();

    }

d[k] = c[l-1].getName();

e[k] = c[l-1].getPrice();

f[k] = c[l-1].getBusload();

g[k] = c[l-1].getCargoload();

    

}

System.out.println("请输入您想要租的天数:");

int n = input.nextInt();

while( n <= 0) {

System.out.println("您输入的信息有误,请重试");

n = input.nextInt();

}

System.out.println("您的账单为:");

System.out.println("****************");

int s = 0;

int sumBusload = 0;

int sumCargoload =0;

int sumPrice=0;

System.out.println("您租的车为:");

for(int j=0;j<d.length;j++) {

System.out.println(d[j]);

}

System.out.println("****************");

for(int j=0;j<f.length;j++) {

s=f[j];

sumBusload = sumBusload + s;

}

System.out.println("载客量共计为:"+sumBusload+"人");

System.out.println("****************");

for(int j=0;j<g.length;j++) {

s=g[j];

sumCargoload = sumCargoload + s;

}

System.out.println("载货量共计为:"+sumCargoload+"吨");

System.out.println("****************");

for(int j=0;j<e.length;j++) {

s=e[j];

sumPrice = sumPrice + s;

}

System.out.println("您共计应花费为:"+(sumPrice*n)+"元");

System.out.println("****************");

System.out.println("感谢您使用答答租车系统!");

System.out.println("欢迎您再次光临!");

}

}
