Question

8.10 LAB: Middle item Given a set of data, output the middle item (if even number of items, output the two middle items). Assume that the data set will always contain less than 20 items. Ex: If the input is 579 11 13-1 (a negative indicates end), the output is: Ex: If the input is 57 911-1, the output is: 7 9 Hint: First read the data into an array. Then, based on the array's size, find the middle item(s)

Answer 1

import java.util.Scanner;

public class LabProgram {

    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        int[] userList = new int[20];
        int numValues;
        int curValue;

        numValues = 0;
        curValue = scnr.nextInt();

        while (curValue != -1) {
            userList[numValues++] = curValue;
            curValue = scnr.nextInt();
        }

        if (numValues % 2 == 1) {
            System.out.println(userList[numValues / 2]);
        } else {
            System.out.println(userList[(numValues - 1) / 2] + " " + userList[numValues / 2]);
        }
    }
