Question

Assign numMatches with the number of elements in userValues that equal matchValue. userValues has NUM_VALS elements. Ex: If userValues is {2, 1, 2, 2} and matchValue is 2 , then numMatches should be 3. Your code will be tested with the following values: userValues: {2, 1, 2, 2}, matchValue: 2 userValues: {0, 0, 0, 0}, matchValue: 0 userValues: {20, 50, 70, 100}, matchValue: 10 import java.util.Scanner; public class FindMatchValue { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); final int NUM_VALS = 4; int[] userValues = new int[NUM_VALS]; int i; int matchValue; int numMatches = -99; // Assign numMatches with 0 before your for loop matchValue = scnr.nextInt(); for (i = 0; i < userValues.length; ++i) { userValues[i] = scnr.nextInt(); } /* Your solution goes here */ System.out.println("matchValue: " + matchValue + ", numMatches: " + numMatches); } }

Answer:

import java.util.Scanner;

public class FindMatchValue {

  public static void main (String [] args) {

     Scanner scnr = new Scanner(System.in);

     final int NUM_VALS = 4;

     int[] userValues = new int[NUM_VALS];

     int i;

     int matchValue;

     int numMatches = -99; // Assign numMatches with 0 before your for loop

     matchValue = scnr.nextInt();

     for (i = 0; i < userValues.length; ++i) {

        userValues[i] = scnr.nextInt();

     }

     /* Your solution goes here */

         numMatches = 0;

     for (i = 0; i < userValues.length; ++i) {

        if(userValues[i] == matchValue) {

                       numMatches++;

                }

     }

     System.out.println("matchValue: " + matchValue + ", numMatches: " + numMatches);

  }

}
