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

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

Step-by-step 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.
