[FIXED] How to remove last comma

Issue

public class Main {

  public static void main(String[] args) {

    // positive number
    int number = 6;

    System.out.print("Factors of " + number + " are: ");

    // loop runs from 1 to 60
    for (int i = 1; i <= number; ++i) {

      // if number is divided by i
      // i is the factor
      if (number % i == 0) {
        System.out.print(i + ",");
      }
    }
  }
}

And my output is "1,2,3,6," but i want it like "1,2,3,6" How can i do that?

No matter what i do it did not worked.

Solution

There are multiple ways to solve it. In your case since the last 'i' in the loop is always number itself, and it should be on the list since (number%number==0), you can simply do something like this:

public class Main {

  public static void main(String[] args) {

    // positive number
    int number = 6;

    System.out.print("Factors of " + number + " are: ");

    // loop runs from 1 to 60
    for (int i = 1; i < number; ++i) { //< instead of <=, to exclude i==number

      // if number is divided by i
      // i is the factor
      if (number % i == 0) {
        System.out.print(i + ",");
      }
    }
      //in your case
      System.out.print(number);
  }
}
