Chapter 15, Problem 9E

Explanation of Solution

Adding the “maxCount” methods in “ArrayIntList” class:

//definition of "ArrayIntList" class

public class ArrayIntList

{

    //declare the required variables

    private int[] elementData;

    private int size;

    //refer the remaining methods in the textbook

    //definition of "maxCount" method

    public int maxCount(int[] arr)

    {

        //declare the variables and set the values

        int counter = 0, count = 0;

/*iterate "i" until it reaches the length of an array*/

        for (int i = 0; i < arr.length; i++)

        {

            //set the value

            count = 0;

/*iterate "j" until it reaches the length of an array*/

            for (int j = i; j < arr.length; j++)

            {

                //check the condition

                if (arr[i] == arr[j])

                {

                    //increment the value

                    count++;
