Define the Circle2D class that contains:

■ Two double data fields named x and y that specify the center of the circle with getter methods.

■ A data field radius with a getter method.

■ A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1

for radius.

■ A constructor that creates a circle with the specified x, y, and radius.

■ A method getArea() that returns the area of the circle.

■ A method getPerimeter() that returns the perimeter of the circle.

■ A method contains(double x, double y) that returns true if the

specified point (x, y) is inside this circle (see Figure 10.21a).

■ A method contains(Circle2D circle) that returns true if the specified circle is inside this circle (see Figure 10.21b).

■ A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle (see Figure 10.21c).

Use the following code for the methods contains and overlaps: 

  public boolean contains(double x, double y) {

    // MyPoint is defined in Exercise09_04

    double d = distance(x, y, this.x, this.y) ;

    return d <= radius;

  }

  public boolean contains(Circle2D circle) {  

    double d = distance(this.x, this.y, circle.x, circle.y);

    return d + circle.radius <= this.radius;

  }

  public boolean overlaps(Circle2D circle) {   

    // Two circles overlap if the distance between the two centers

    // are less than or equal to this.radius + circle.radius

    // MyPoint is defined in Exercise09_04

    return distance(this.x, this.y, circle.x, circle.y)

      <= radius + circle.radius;

  }

  private static double distance(double x1, double y1,

      double x2, double y2) {

    return Math.sqrt((x1 - x2) * (x1 - x2) + (y1 - y2) * (y1 - y2));

  } 

Here is a sample run for a point 2, 2 with a radius of 5.5:
