问答题

【说明】
下面的程序先构造Point类，再顺序构造Ball类。由于在类Ball中不能直接存取类Point中的xCoordinate及yCoordinate属性值，Ball中的toString方法调用Point类中的toStrinS方法输出中心点的值。在MovingBsll类的toString方法中，super.toString调用父类Ball的toString方法输出类Ball中声明的属性值。
【Java代码】
//Point.java文件
public class Point
private double xCoordinate;
private double yCoordinate；
public Point()
public Point(double x,double y)
xCoordinate=x;
yCoordinate=y;

public String toStrthg()
return"("+Double.toString(xCoordinate)+","
+Double.toString(yCoordinate)+")";

//other methods

//Ball.java文件
public class Ball
private (1) ;//中心点
private double radius;//半径
private String color;//颜色
public Ball()
public Ball(double xValue, double yValue, double r)
//具有中心点及其半径的构造方法
center= (2) ;//调用类Point中的构造方法
radius=r;

public Ball(double xValue, double yValue, double r, String c)
//具有中心点、半径和颜色的构造方法
(3) ;//调用3个参数的构造方法
color=c;

public String toString()
return "A ball with center"+center.toString()
+",radius "+Double.toString(radius)+",color"+color;

//other methods

class MovingBall (4)
private double speed;
public MovingBall()
public MoyingBall(double xValue, double yValue, double r, String c, double s)
　 (5) ;//调用父类Ball中具有4个参数的构造方法
speed=s;

public String toString()
return super.toString()+",speed"+Double.toString(speed);

//other methods

public class test
public static void main(String args[])
MovingBall mb=new MovingBall(10,20,40,"green",25);
System.out.println(mb);
