For Java.

Write a method called doubleQueue that accepts a class that implements the Queue interface, and replaces every element of the queue with two copies of that element. Please hard-code three test cases into your program: [6,3,4] becomes [6,6,3,3,4,4, ["a", "b", "cod"] becomes [ "a", "a", "b", "b", "cod", "cod"] [5,6,7,8,9] becomes [5,5,6,6,7,7,8,8,9,9] However, your doublequeue routine must work for any queue data, not just the test cases. Java queue reference: https://docs.oracle.com/javase/7/docs/api/java/util/Queue.html Please note: java. util.Queue is an interface. Please choose one of the implementing classes to instantiate Queue-like objects and call the relevant methods specified by the interface. You are not expected to implement the Queue interface for this lab
