JAVA入门第二季-哒哒租车系统

总的所有车的父类

public class car {
    protected String name;
    protected int money;

    public String getname(){
        return name;
    }

    public int getmoney(){
        return money;
    }

    public void setname(){
        this.name=name;
    }

    public void setmoney(){
        this.money=money;
    }

    public void car(String name,int money){
        this.name=name;
        this.money=money;
    }
    public void dayin(){

    }
}

接下来是汽车类

public class qiche extends car {
    protected int zaikeliang;

    public int getzaikeliang(){
        return zaikeliang;
    }

    public void setzaikeliang(int zaikeliang){
        this.zaikeliang=zaikeliang;
    }

    public qiche(String name,int money,int zaikeliang){
        this.name=name;
        this.money=money;
        this.zaikeliang=zaikeliang;
    }

    public void dayin(){
        System.out.println("\t"+name+"\t"+money+"元/天 "+"\t"+"载人："+zaikeliang+"人");
    }
}

然后是货车类

public class huoche extends car {
    protected int zaihuoliang;

    public int getzaihuoliang() {
        return zaihuoliang;
    }

    public void setzaihuoliang(int zaihuoliang) {
        this.zaihuoliang=zaihuoliang;
    }

    public huoche(String name,int money,int zaihuoliang){
        this.name=name;
        this.money=money;
        this.zaihuoliang=zaihuoliang;
    }

    public void dayin(){
        System.out.println("\t"+name+"\t"+money+"元/天            "+"\t"+"载货："+zaihuoliang+"吨");
    }
}

接着是皮卡类

public class pika extends car {
       protected int zaikeliang;
       protected int zaihuoliang;

        public int getzaikeliang(){
            return zaikeliang;
        }

        public void setzaikeliang(){
            this.zaikeliang=zaikeliang;
        }
        public int getzaihuoliang(){
            return zaihuoliang;
        }

        public void setzaihuoliang(){
            this.zaihuoliang=zaihuoliang;
        }

        public pika(String name,int money,int zaikeliang,int zaihuoliang){
            this.name=name;
            this.money=money;
            this.zaikeliang=zaikeliang;
            this.zaihuoliang=zaihuoliang;
        }

        public void dayin(){
            System.out.println("\t"+name+"\t"+money+"元/天     "+"\t"+"载人："+zaikeliang+"人    "+"载货："+zaihuoliang+"吨");
        }
}

最后是总的程序的运行部分

import java.util.*;
public class qichezulin {
    public static void main(String[] args) {
        System.out.println("--------欢迎进入哒哒租车系统--------");
        System.out.println("            您是否要租车                               ");
        System.out.println("             1-是   0-否                                  ");
        Scanner input=new Scanner(System.in);
        int a=input.nextInt();
        while(true){
            if(a!=0&&a!=1){
                System.out.println("      您输入有误    请重新输入           ");
            }
            else
                break;
            a=input.nextInt();
        }
        if(a==0){
            System.out.println("------------欢迎下次再来------------");
        }
        if(a==1){
            System.out.println("------------租车清单如下------------");   
            System.out.println("序号        汽车名称           租金                              容量");
            car cars[]={

                    new qiche("金龙        ", 800,  20),

                    new huoche("依维柯   ", 1000, 20),
                    new pika("皮卡雪6 ", 450, 4, 2)
            };
            for(int i=0;i<cars.length;i++){
                System.out.print(i+1);
                cars[i].dayin();
            }
            System.out.println("          请输入租车数量：                            ");
            int number=input.nextInt();
