Submit Lab3.java, Lab3.jar, screen shots of results, and this word file (completed version) for lab3.
Problem Description:
Define the Circle2D class that contains:
- one Point2D.Double data field named center that specifies the center of the circle with get and set methods.
- A data field radius with a get method.
- A default constructor that creates a default circle with (0, 0) for (x, y) of the center and 1 for radius.
- A constructor that creates a circle with the specified x, y, and radius, where (x,y) is the center cordinates.
- A constructor that creates a circle with the specified p and radius, where p is the center as Point2D.Double.
- A method area() that returns the area of the circle.
- A method perimeter() 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 10.14(a).
- A method contains (Point2D.Double p) that returns true if the specified point p is inside this circle.
- A method contains (Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b).
- A method overlaps (Circle2D circle) that returns true if the specified circle overlaps with this circle. See Figure 10.14(c).
- A method disjoints (Circle2D circle) that returns true if the specified circle does not intersect with this circle. See Figure 10.14(d).
- A method tangent (Circle2D circle) that returns true if the specified circle and this circle tangent to each other. See Figure 10.14(d).

3. Testing
public class Lab3 {
public static void main(String[] args) {
System.out.println("Lab3: Your name");
Circle2D c1 = new Circle2D(2, 2, 5.5);
System.out.println("Area of c1 is: " + c1.area());
System.out.println("Perimeter of c1 is: " + c1.perimeter());
System.out.println("c1.contains(3, 3) is: " + c1.contains(3, 3));
System.out.println(("c1.contains(new Circle2D(4, 5, 10.5)) is: " +
c1.contains(new Circle2D(4, 5, 10.5)));
//add code to test the rest of the methods of Circle2D.
}
