Question

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 int[NUM_VALS];
      int i;

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

      /* Your solution goes here */

      System.out.println("");
   }
}

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 int[NUM_VALS];
        int i;

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

        for (i = 0; i < hourlyTemp.length; ++i) {
            System.out.print(hourlyTemp[i]);
            if (i < hourlyTemp.length-1) {
                System.out.print(", ");
            }
        }

        System.out.println("");
    }
}
