[多项选择]【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toString方法输出中心点的值。在MovingBall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。
public class Point
private double xCoordinate;
private double yCoordinate;
public Point 0
public Point(ouble x, double y)
xCoordinate = x;
yCoordinate = y;
public String toString( )
return "( + Double.toString(Coordinate)+ ","
+ Double.toString(Coordinate) + ");
//other methods
public class Ball
(1) ; //中心点
private double radius; //半径
private String colour; ///颜色
public Ball( )
public Ball(double xValue, double yValue, double r)// 具有中心点及半径的构造方法
center= (2) ;//调用类Point 中的构造方法
radius = r;
public Ball(double xValue, double yValue, double r, String c)

[简答题]【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。
