Java实现MVC球体
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();
}
}
