This method will return an ArrayList. When called and passed anArrayList, this method will return an ArrayList containing all the elements in the argument ArrayList that are in the argument ArrayList more than one time. Each duplicate value must appear in the returned array only once. The values in the returned ArrayList must be in the same order as they first appear in the the argument ArrayList. Here are some examples: Example 1 Given: ArrayListmyList = new ArrayList>(); with these values {1,2,3,4,5}; allDuplicates (myList) should return an ArrayList with these values \{\} Example 2 Given: ArrayList myList = new ArrayList>(); with these values {3,2,3,1,4,2,1,3,0}; allouplicates (myList) should return an ArrayList with these values {3,2,1} Example 3 Given: ArrayList myList = new ArrayList>(); with these values {1,1,1}; allDuplicates (myList) should return an ArrayList with these values {1} Helpful Info: - You may want to write a main method to call and test your required method
