1. 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:
matchValue: 2, userValues: {2, 1, 2, 2} (as in the example program
above)
matchValue: 0, userValues: {0, 0, 0, 0}
matchValue: 10, userValues: {20, 50, 70, 100}
What i am given:
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);
}
}
2. Write a for loop to populate array userGuesses with NUM_GUESSES integers. Read integers using Scanner. Ex: If NUM_GUESSES is 3 and user enters 9 5 2, then userGuesses is {9, 5, 2}.
What I am given
import java.util.Scanner;
public class StoreGuesses {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_GUESSES = 3;
int[] userGuesses = new int[NUM_GUESSES];
int i;
/* Your solution goes here */
for (i = 0; i < userGuesses.length; ++i){
System.out.print(userGuesses[i] + " ");
}
}
}
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(); } numMatches = 0; for (i = 0; i < userValues.length; ++i) { if(matchValue == userValues[i]){ numMatches+=1; } } System.out.println("matchValue: " + matchValue + ", numMatches: " + numMatches); } }

Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print: 90, 92, 94, 95 Your code's output should end with the last element, without a subsequent comma, space, or newline. import java.util.Scanner; public class PrintWithComma { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); final int NUM_VALS = 4; int[] hourlyTemp = new...
Assign numMatches with the number of elements in userValues that equal matchValue. userValues has NUM_VALS elements. Ex: If userValues is {2, 2, 1, 2} and matchValue is 2 , then numMatches should be 3.

7.2.3: Printing array elements with a for loop. Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = courseGrades.length - 1.
