Write a method called allUnique that takes an array of integers as a parameter and returns a boolean that is false if the array has any duplicate values and is true if all elements in the array are unique. For example, if the array contains the int values 2, 3, 5, 2, 8 then the method should return false, but if the array contains the int values 5, 4, 2, 3, 1 then the method should return true.

Just submit the definition of the method itself, not the main program that tests it. But you are strongly recommended to test the code using either Eclipse or Processing.
