please help me modify the circle class to include an overload constructor that accepts the radius of the Circle object..

/**

* Circle class.

*/

public class Circle {

private static final double PI= 3.14;

private double radius;

/**

* constructor

* pre: none

* post: A circle object created. Radius initialized to 1.

*/

public Circle() {

radius = 1; //default radius

}

/**

* Changes the radius of the circle.

* pre: none

* post: Radius has been changed.

*/

public void setRadius (double newRadius) {

radius = newRadius;

}

/**

* Calculates the circumference of the circle

* pre: none

* post: The circumference of the circle has been returned.

*/

public double circumference() {

double circleCircumference;

circleCircumference = 2 * PI * radius;

return(circleCircumference);

}

/**

* Returns the radius of the circle.

* pre: none

* post: The radius of the circle has been returned.

*/

public double getRadius() {

return(radius);

}
