Question

Set numMatches to the number of elements in userValues (having NUM_VALS elements) that equal matchValue. Ex: If matchValue = 2 and userValues = {2, 2, 1, 2}, then numMatches = 3.
import java.util.Scanner;
public class FindMatchValue {
public static void main (String [] args) {
final int NUM_VALS = 4;
int[] userValues = new int[NUM_VALS];
int i = 0;
int matchValue = 0;
int numMatches = -99; // Assign numMatches with 0 before your for loop
userValues[0] = 2;
userValues[1] = 2;
userValues[2] = 1;
userValues[3] = 2;
matchValue = 2;

Answer 1

Answer:

import java.util.Scanner;

public class FindMatchValue {

public static void main (String [] args) {

   final int NUM_VALS = 4;

   int[] userValues = new int[NUM_VALS];

   int i = 0;

   int matchValue = 0;

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

   userValues[0] = 2;

   userValues[1] = 2;

   userValues[2] = 1;

   userValues[3] = 2;

   matchValue = 2;

   numMatches=0;

   for(i=0;i<NUM_VALS;i++)

   {

       if(userValues[i]==matchValue)//cheking if the array element is equal to match value.

       {

           numMatches++;

           

       }

   }

   System.out.println(numMatches);//printing the matchvalue.

}

}

Output:-

3

Explanation:

First I have set the value numMatches to 0 before the loop.Then I have user the for loop to iterate over the array.In the for loop I am checking that the array element is equal to the matchValue or not if it is equal then increasing the numMatches by 1.Then at last print the value of numMatches.
