I need the the solution of problem number 11(using bubble sort) description is in the pictures and the reference code also given.

11. Ascending Circles Program 8-31 from Chapter 8 creates an array of four Circle objects, then displays the area of each object. Using a copy of that program as a starting point, modify it to create an array of seven Circle objects initialized with the following radii: 2.5, 4.0, 1.0, 3.0, 6.0, 5.5, 2.0. Then use a bubble sort to arrange the objects in ascending order of radius size before displaying the area of each object
