Chapter 11.1, Problem 9SCP

Explanation of Solution

Program:

//define the static function

public static int countDuplicates(List<Integer> list) {

    //declare and initialize the variable

    int count = 0;

    //assign the value

    Iterator<Integer> i = list.iterator();

    int prev = i.next();

    //loop initialized to print values

    while (i.hasNext()) {

        //assign the value

        int next = i.next();

        //condition is initialized to check whether the value of prev is equal to next

        if (prev == next) {

            //increment the value
