Write a method called fromCounts that constructs and returns a new Array IntList of values given an existing ArrayIntList of counts. Assume that the ArrayIntList that is passed as a parameter stores a sequence of integer pairs that each indicate a count and a number. For example, suppose that an ArrayIntList called list stores [5,2,2,5,4,3,2,4,1,1,1,0,2,17]. We will interpret this sequence of pairs to mean that you have 5 occurrences of 2 , followed by two occurrences of 5 followed by 4 occurrences of 3 , and so on. So the call of: ArrayIntList list2 = list. fromCounts () should cause the variable list2 to store [2,2,2,2,2,5,5,3,3,3,3,4,4,1,0,17,17]. Assume you are adding to the ArrayIntList class with following fields: public class ArrayIntList \{ private int [] elementData; private int size; // your code goes here
