Write a public static method named lessThanAverage that will take an ArrayList<Integer> as an argument. This method will return an ArrayList<Integer>. When called and passed anArrayList, this method will return an ArrayList containing all the elements in the argument ArrayList that are less than the average of all the values in the argument ArrayList. The values in the returned ArrayList must be in the same order as they are in the argument ArrayList. Here are some examples: Example 1 Given: ArrayList<Integer> myList = new ArrayList<Integer>(); with these values {1, 2, 3, 4, 5}; lessThanAverage (myList) should return an ArrayList<Integer> with these values {1, 2} Example 2 Given: ArrayList<Integer> myList new ArrayList<Integer>(); with these values {3, 7, 6, 2, 9, 0, 4, 8}; lessThanAverage (myList) should return an ArrayList<Integer> with these values {3, 2, 0, 4} Example 3 = Given: ArrayList<Integer> myList new ArrayList<Integer>(); with these values (1, 1, 1}; less ThanAverage (myList) should return an ArrayList<Integer> with these values { } Helpful Info: • You may want to write a main method to call and test your required method = Activate Windows Go to Settings to activate Windows 2:50 AM Problem Description and Given Info Write a public static method named allUnique that will take an ArrayList<Integer> as an argument.
