Question

in java

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;

/* student solution goes here */

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

return;
}
}

Explanation / Answer

FindMatchValue.java

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;

/* student solution goes here */
numMatches=0;
  
for(i=0;i<userValues.length;i++)
{
   if(matchValue==userValues[i])
   {
       numMatches++;
   }
}
  
//Displaying the result
System.out.println("matchValue: " + matchValue + ", numMatches: " + numMatches);
return;
}
}

output:

matchValue: 2, numMatches: 3
