Modifying this app.

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);
}

That's not really how this works. What have you tried? Why are you stuck? What worked, what didn't work? How didn't it work? Ask a specific question, and we'll go from there. This isn't a code service.

We can't help you until you tell us specifically what problems you are having. Until then, the original post is not much more than a code/homework dump.

Two in a row, though.
Will we get a hat-trick?

We sure will.

We sure will.

Hurrah!

Though technically that's a different scorer...:)
