Write a program (

RadixSortAnimation.java

) that animates the radix sort algorithm.

Create an array that consists of 20 random integers from 0 to 999, inclusive. The array

elements are displayed, as shown in Figure 0. Clicking the Step button causes the

program to place a number in a bucket. The number that has just been placed is displayed

in red, as shown in Figure 1. Once all the numbers are placed in the buckets, clicking the Step

button collects all the numbers from the buckets and moves them back to the array,

as shown in Figure 2. When the algorithm is finished, clicking the Step button displays a

message to inform the user, as shown in Figure 3. Clicking the Reset button creates a new

random array for a new start.
