Extracted text: Write a method called randomNumber that takes as purumeter an integer n and returns a random integer between 1 and n inclusive that is a multiple of 3 (Hint: keep generating an integer using a loop until a multiple of 3 is found). Write a test program that reads from the user an integer greater than 20 then uses the above method to generate five random integers (must use a loop). The program displays the numbers generated. Sample Run 1: Enter an integer greater than 20: 40 | The random numbers generated as multiples of 3 are: 159 18 6 33 Sample Run 2: Enter an integer greater than 20: 15 15 is not valid!
