For version 3, you will also prevent a duplicate entry (a number that has already been entered). You must use a new method other than main to validate that the number entered is unique. Also use the Arrays.sort method to sort the contents of the array. Make a copy of version 2 of your program and make the following changes: Name the class Lottery3 Continue to use the main method to manage the loops and main flow control. .Use the library class Arrays and its "sort" method to sort the array after all lottery numbers are selected Create a method called isUnique which accepts two parameters, an int containing the number that was entered, and an array of ints containing all the values previously entered. The method should return a boolean indicating whether or not the number passed unique. If false is returned, display a message from the main method indicating that the user must try again. Continue to loop and allow repeated attempts until a valid value is captured. public static boolean isUnique (int theNumber, int[] allNumbers) SAMPLE OUTPUT: java Lottery3 Enter a number from 1-54 (pick #1): 15 Enter a number from 1-54 (pick #2): 2 Enter a number from 1-54 (pick #3): 15 ERROR=> Duplicate number.
