  Method public IntList (int size) private int indexof (int searchingNum) Description of the Method The constructor instantiates an array of integers using the given size This method returns the index where searchingNum is located. It returms -1 ifit is not found. It checks if the array has not reached its capacity, the num is added to the array at the smallest available index This is a helper method; it is private and it doubles the size of the arra It returns the largest integer stored in the array, f no element stored in the array, it returns zero It returns the smallest integer stored in the array, if no element stored in the array, it returns zero public void addInt (int num) private void doubleArrayCapacity ( public int findMax () public int findMin () Removes the first occurrence of num from the list and moves all elements one spot to the left. It will leave the array the same if num is not in the list to be removed Removes all the occurrence of num from the array and shifts all the elements to the left by one index this method returns an array of all the integers that are public void removeFirst (int num) public void removeAll (int num) public int[] countNumbers (int num) public String toString () ater than num Displays the array of integers. It prints 10 integers per line, in this format [6, 7, 8,91- see the sample output
