Task:
1. Define a class named Circle.
2. A Circle object stores a radius and the (x, y) coordinates of its center point using Point class (Point class should be similar to the one we wrote during lectures. It should have at least two private fields to store x and y coordinates of a point, one constructor, a toString method and a distance method).
3. Each Circle object should have 2 private fields, a Point object and radius. Each Circle Object should have the following public method:
Circle (p-radius)
Constructs a new circle with a center specified by the given Point p and with the given integer radius.
getcentert ()
Returns point object for the center of the circle.
getRadius ()
Returns the circle's radius.
getArea ()
Returns the area occupied by the circle, using the formula pir2.
get circumference ()
Returns the circle's circumference (distance around the circle), using the formula 2nr.
teostring ()
Returns a string representation of the circle, such as "Circle [center=(75, 20), radius=30]".
contains (p)
Returns true if the point p lies within the circle else returns false. (Hint: calculate the distance between the center and the point p and compare it with the radius).
Write a client class named CircleClient. It should create an object of class Circle and initialize it to point (10,5) and radius 7. Print the object. Print out its circumference and area. If point (5,7) lies within the circle print "(5,7) lies within the circle" else print "(5,7) does not lie within the circle".
