Make a JavaFX application - CircleOverlap.java - that presents 20 circles (use the JavaFX Circle class), each with a random radius and location. If a circle does not overlap any other circle, fill the circle with a Color of your choice (I used black but you don't have to). Fill overlapping circles with a translucent blue (alpha value of 0.3).
In addition, ensure the entire circle appears in the visible area of the Scene (no circle should go off the edge).
Note 1: start() and main() are the only methods required.
Note 2: Use an array to store the Circle objects, and check each new circle to see if it overlaps any previously created circle. DO NOT use an ArrayList.
Reminder 1: Two circles overlap if the distance between their center points is less than the sum of their radii.
Reminder 2: The distance between two points (x1,y1) and (x2,y2) on a flat surface is:
    ____________________
   /       2          2
 / (y2-y1)  + (x2-x1)
