答答租车系统

//新手初次动手，有不对的地方还请各位前辈指正，谢谢大家！
//这个系统我一共用了5个文件，具体其中都有注释，这是第一个

//创建抽象类，定义车辆共有属性和方法
public abstract class Car {
    
    public int id;
    
    public String name;
    
    public int rent;
    
    public abstract void information();
}

第二个

//皮卡车子类，继承父类车的属性和方法，并有自己的属性载人量和载货量
public class Pickup extends Car {
    
    public int manned;
    
    public int loading;
    
    public Pickup(int id, String name, int rent, int manned, int loading){
 this.id = id;
 this.name = name;
 this.rent = rent;
 this.manned = manned;
 this.loading = loading;
    }
    @Override
    public void information() {
 // 输出皮卡车信息
 System.out.println(id + ".t" + name + "t " + rent + "元/天" + "载人：" + manned + "人，" + "载货：" + loading + "吨");
    }
}

第三个

//货车子类，继承父类车的属性和方法，并有自己的属性载货量
public class Truck extends Car {
    
    public int loading;
    
    public Truck(int id, String name, int rent, int loading){
 this.id = id;
 this.name = name;
 this.rent = rent;
 this.loading = loading;
    }

    @Override
    public void information() {
 // 输出货车信息
 System.out.println(id + ".t" + name + "t " + rent + "元/天" + "载货：" + loading + "吨");
    }
}

第四个

//客车子类，继承父类车的属性和方法，并有自己的属性载人量
public class Bus extends Car {
    
    public int manned;

    
    public Bus(int id,String name, int rent,int manned){
 this.id = id;
 this.name = name;
 this.rent = rent;
 this.manned = manned;
    }
    @Override
    public void information() {
 // 输出客车信息
 System.out.println(id + ".t" + name + "t " + rent + "元/天" + "载人：" + manned + "人");
    }
}
