The Circle Class

The Circle class has two fields: radius, a double that represents the radius of the circle, and origin, a Point object that represents the coordinates of the center of the circle.

Your job is to implement the three methods of the circle class. The first of which of course being the constructor, which takes the double radius and the Point origin as arguments. The last two methods are both named .pointFromAngle() and both return a Point object that represents a point on the circumference of the circle when given an angle.

The difference between the two .pointFromAngle() methods is that one takes the int degrees for its angle and the other takes the double radians.

Preloaded for you is the Point class.

public class Point{
 public double x,y;
 public Point(double x, double y){
 this.x = x;
 this.y = y;
 }
}

For testing purposes, Point also includes .toString() and .equals(), the latter of which accepting a small margin of error to account for the inexactness of doubles.

Finding a Point Using an Angle

Remember that on a radius 1 circle, the x value of a point is the cosine of its angle and the y value of the point is the sine of its angle. Do not forget to consider the position of the circle's origin and its radius.

Assumptions

• radius will always be greater than 0.
• degrees will always be between 0 inclusively and 360 exclusively.
• radians will always be between 0 inclusively and 2π exclusively.
• x and y will both be between -1000 and 1000.
