今天完成了广告界面的设计，

通过上网查询，了解到互联网广告投放一般按照天数计费，费用高低不一，通常有几种模式：季度收费，按年收费，天数计费等。

通过钟表计算广告运行的天数，来进行广告收益的计算，再将广告信息传输到数据库进行存储。

advertBean.java

package com.example.math.bean;

public class advertBean {
    private String advert_name;
    private float price;
    private String time;

    public advertBean(String advert_name, float price, String time) {
        this.advert_name = advert_name;
        this.price = price;
        this.time = time;
    }

    public String getAdvert_name() {
        return advert_name;
    }

    public void setAdvert_name(String advert_name) {
        this.advert_name = advert_name;
    }

    public float getPrice() {
        return price;
    }

    public void setPrice(float price) {
        this.price = price;
    }

    public String getTime() {
        return time;
    }

    public void setTime(String time) {
        this.time = time;
    }
}
