Question

integer matchvalue is read from input. then, array uservalues is assigned with num_vals integers read from input. organize the lines of code to assign nummatches with the number of elements in uservalues that equal matchvalue. ex: if the input is: 2 2 1 2 2 then the output is: matchvalue: 2, nummatches: 3 how to use this tool unused for (i = 0; i < uservalues.length; ++i) { } nummatches = nummatches + 1; if (uservaluesi == matchvalue) { } nummatches = 0; findmatchvalue.java 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 intnum_vals; int i; int matchvalue; int nummatches; matchvalue = scnr.nextint(); for (i = 0; i < uservalues.length; ++i) { uservaluesi = scnr.nextint(); }

Explanation:

Step1: Initialize numMatches

numMatches = 0;

Step2: Iterate through userValues

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

Step3: Check for match

if (userValues[i] == matchValue) {

Step4: Increment numMatches

numMatches = numMatches + 1;

Step5: End loop

}

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;

        matchValue = scnr.nextInt();
        for (i = 0; i < userValues.length; ++i) {
            userValues[i] = scnr.nextInt();
        }

        numMatches = 0;
        for (i = 0; i < userValues.length; ++i) {
            if (userValues[i] == matchValue) {
                numMatches = numMatches + 1;
            }
        }

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