Eliminate the last comma in the string output which

Question

Eliminate the last comma in the String Output which includes array output values from "hourlyTemp[i]" (entire list). My guess is that this needs to incorporate "%d" somehow but my online book won't accept the use of "%d" for some reason. From the book: Quoted 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

Note 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;

for (i = 0; i System.out.print(hourlyTemp[i] + ", ");

}

System.out.println("");

return;

}

}
