Use operators to construct an expression

Declare and instantiate an ArrayList

Access ArrayList elements by index

Write a method according to given specifications

Write a method that takes arguments and returns a value

Write a method that takes an ArrayList as an argument

Write a method that returns an ArrayList

Problem Description and Given Info

Write a public static method named allDuplicates that will take an ArrayList as an argument. 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: ArrayList myList = 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};

allDuplicates(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}
