java实现KFC点餐小程序

java实现KFC点餐小程序

本文实例为大家分享了java实现KFC点餐系统的具体代码，供大家参考，具体内容如下

package KFC点餐系统;

//food 类

public class Kfcfood {

private String fname ;

private int fnumb=1;

private float fPrice;

public Kfcfood() {

super();

}

public Kfcfood(String fname, int fnumb, float fPrice) {

super();

this.fname = fname;

this.fnumb = fnumb;

this.fPrice = fPrice;

}

public String getFname() {

return fname;

}

public void setFname(String fname) {

this.fname = fname;

}

public int getFnumb() {

return fnumb;

}

public void setFnumb(int fnumb) {

this.fnumb = fnumb;

}

public float getfPrice() {

return fPrice*fnumb;

}

public void setfPrice(float fPrice) {

this.fPrice = fPrice;

}

@Override

public String toString() {

return fname + " 价格 [" + fPrice + "]";

}

}

package KFC点餐系统;

/*

* 1.正常餐品结算和找零。

2.基本套餐结算和找零。

3.使用优惠劵购买餐品结算和找零。

4.可在一定时间段参与店内活动（自行设计或参考官网信息）。

5.模拟打印小票的功能（写到文件中）。

*

* 本人写这个小程序，第一创建Kfcfood类属性有foodname foodPrice foodnumb 和一些必要函数 这个类负责封装食物属性

* Demo1 是主程序 核心 是HashMap 集合，HashMap 做购物车 添加食物 和遍历打印小票

* 用字符输出流 很简洁的写法写入文本

* BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("out.txt",true)));//字符缓冲输出流
