Chapter 15, Problem 2E

Explanation of Solution

Adding the “indexOfSubList” 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 "indexOfSubList" method

    public int indexOfSubList(ArrayIntList sublist)

    {

        //iterate "i" until it reaches an array value

        for (int i = 0; i < size - sublist.size; i++)

        {

            //declare the variable

            boolean match = true;

/*iterate "j" until it reaches an array value*/

for (int j = 0; j < sublist.size && match; j++)

            {

                //check the condition

if (elementData[i + j] != sublist.elementData[j])

                {

                    //set the value

                    match = false;
