Java实现一个模型、两个视图和两个控制器的功能软件，即采用MVC模式或者说是观察者模式，本程序通过输入球体半径，显示球体形状，面积体积等
Sphere.java
package Model;
import java.util.Observable;
public class Sphere extends Observable {
private double radius;//球体半径
private double area;//球体面积
private double volume;//球体体积
public Sphere()
{
radius=100d;
area=4*Math.PI*Math.pow(radius, 2);
volume=4*Math.PI*Math.pow(radius, 3)/3;
}
public double getRadius()
{
return radius;
}
public double getArea()
{
return area;
}
public double getVolume()
{
return volume;
}
public void setRadius(double radius)
{
this.radius = radius;
this.area = 4*Math.PI*Math.pow(radius, 2);
this.volume=4*Math.PI*Math.pow(radius, 3)/3;
this.setChanged();
this.notifyObservers();
}
}

请根据观察者模式，用Java语言设计并实现气象站程序。其中，部分代码已经写好，包括：
• 观察者接口
• 主题接口
• 显示板接口
• 测试程序
请在此框架下，继续完成CurrentConditionsDisplay、ForecastDisplay、StatisticsDisplay等显示板类，
以及气象数据类（WeatherData），
使程序最终运行结果如下图所示（XXXX为本人学号）：
Currents conditions:80.0F degress and 65.0% humidity (by 1508060330)
Avg/Max/Min:temperature = 80.0/80.0/80.0/ (by 1508060330)
Forecast (by 1508060330):improving weather on the way
Currents conditions:82.0F degress and 70.0% humidity (by 1508060330)
Avg/Max/Min:temperature = 81.0/82.0/80.0/ (by 1508060330)
Forecast (by 1508060330):watch out for cooler,rainy weather
Currents conditions:78.0F degress and 90.0% humidity (by 1508060330)
Avg/Max/Min:temperature = 80.0/82.0/78.0/ (by 1508060330)
Forecast (by 1508060330):more of the same
