Chapter 7, Problem 5E

Explanation of Solution

Method “mod()” to find the repeated integer in the array:

//Definition of class

public class Text {

    //Definition of main method

    public static void main(String[] args)

    {

        //Create an array

        int[] list2={27,15,15,11,27};

        //Call the method mode(list2)

        System.out.println(mode(list2));

    }

    //Definition of method mode()

    public static int mode(int[] a)

    {

        // Crete an array called tally

        int[] tally = new int[101];

        //Traverse the loop till it reaches the length

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

        {

            //Increment the array

            tally[a[i]]++;

        }

        //Declare and initialize the variables

        int count = 0;

        int val = 0;

        //Traverse the loop till it reaches the length

        for (int i = 0; i < tally...
