景区门票计费系统（Java抽象类练习含GUI窗体组件）

景区门票计费系统（Java抽象类练习含GUI窗体组件）

需要为一个景区实现计算景区门票的程序，已知成年人的门票价格是100元，儿童票打3折，老年票打5折。使用抽象类来为任意多张不同类型的票计算总价。其UML类图如下所示。

要求能够输入不同类型门票的数量，输出总的票价。

    float price;

    public Ticket() {
    }

    public Ticket(float price) {
        this.price = price;
    }

    public float getPrice() {
        return price;
    }

    public void setPrice(float price) {
        this.price = price;
    }
 public float singprice(){
            this.price=this.hashCode();
            return this.price;
    }
     public abstract float shouldPay(float totalPrice);    
}

YoungTicket类成人票

    public YoungTicket() {
    }

    public YoungTicket(float price) {
        super(price);
    }

    @Override
    public float shouldPay(float totalPrice) {
        return totalPrice;
    }
    
}

ChildTicket类儿童票

package javaapplication1;

public class ChildTicket extends Ticket{

    public ChildTicket() {
