Write a Java program that generates 30 random numbers (range 1-20 inclusive) and then writes the numbers to a file. Each number in the file should be separated by a | symbol with five numbers per line. No line should begin or end with a | symbol. The program should also write control totals on the last 2 lines of the file, the second last line showing the average number generated, and the last line showing the number(s) that were generated the least amount of times.
