資源簡介
Java實現一個模型、兩個視圖和兩個控制器的功能軟件，即采用MVC模式或者說是觀察者模式，本程序通過輸入球體半徑，顯示球體形狀，面積體積等
Sphere.java
package Model;
import java.util.Observable;
public class Sphere extends Observable {
private double radius;//球體半徑
private double area;//球體面積
private double volume;//球體體積
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();
}
}
