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, 95Note that the last element is not followed by a comma, space, or newline.import java.util.Scanner;public class PrintWithComma {public static void main (String [] args) {final int NUM_VALS = 4;int[] hourlyTemp = new int[NUM_VALS];int i = 0;hourlyTemp[0] = 90;hourlyTemp[1] = 92;hourlyTemp[2] = 94;hourlyTemp[3] = 95;/* Your solution goes here */System.out.println("");return;}}

Answer 1

Answer:

Here are the for loop for the given question.

 for (i = 0; i < NUM_VALS; i++)  // for loop

       {

         /* check if the value of i is equal to NUM_VALS or not.If it is

         equal then just print the value without comma.*/

       if(i==(NUM_VALS-1))  // if block

       System.out.print(hourlyTemp[i]);

  /* if i is not equal then just print the value with comma.*/

       else   // else block

       System.out.print(hourlyTemp[i] + ", ");

       }

Explanation:

In this we iterating the for loop  and check the condition

check if the value of i is equal to NUM_VALS or not.If it is  equal then just print the value without comma

If i is not equal then just print the value with comma .

Output:

90,92,94,95
