Write a method named hasThree that accepts a list of strings as a parameter and returns true if any string value occurs at least 3 times in the list. For example, in the list ["to", "be", "or", "be", "to", "be", "hamlet"], the word "be" occurs 3 times, so your method would return true if passed that list. Use a HashMap as auxiliary storage to help solve the problem. Do not modify the list that is passed in.

Method: Write a Java method as described, not a complete program or class.
