Write a class named DiceGame.java that contains a method called diceSum that prompts the use for a desired sum, then repeatedly simulates the rolling of 2 six-sided dice until their sum is the desired sum (use a do/while loop). Here is a sample dialogue with the user: Desired dice sum: 9 4 and 3 = 7 3 and 5 = 8 5 and 6 = 11 5 and 6 = 11 1 and 5 = 6 6 and 3 = 9 You must perform checks to make sure the user enters an integer between 2 and 12 and reprompt if not. You must also reprompt for non-int values. Your code should include assertion comments for assertions that are always true (provable).
