PP 8.16 Write a JavaFX application that presents 20 circles, each with a random radius and location. If a circle does not overlap any other circle, fill the circle with black. Fill overlapping circles with a translucent blue (alpha value of 0.3). Hint: Use an array to store the Circle objects, and check each new circle to see if it overlaps any previously created circle. Two circles overlap if the distance between their center points is less than the sum of their radii.
