Write a method named repeat that accepts an ArrayList of Strings and an integer k as parameters and that replaces each element with k copies of that element. For example, if the list stores the values ["how", "are", "you?"] before the method is called and k is 4, it should store the values ["how", "how", "how", "how", "are", "are", "are", "are", "you?", "you?", "you?", "you?"] after the method finishes executing. If k is 0 or negative, the list should be empty after the call.

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