Consider the following Java definition of an integer list class.class IntegerList{ private int[] list = new int[200]; private int size = 0; public boolean append(int value) { if (size == list.length) return false; list[size++] = value; return true; } public String toString() { String result = ""; for (int i = 0; i < size; i++) result += list[i] + " "; return result; }}
