How to format multiple string parameters in Java

Question

I'm writing the following for a class assignment:

public class SportsBall {
  public static void printDivision (String divName, String heading1, String heading2) {
    System.out.printf("%-30s", divName + heading1 + heading2);
  }

  public static void main(String[] args) {
    printDivision("bla ", "blahhhh ", "Northwest");
  }
}

The problem I'm having is specifying the length of the strings divName, heading1, and heading2. "%-30s" formats one of them, on either end, but for the life of me, I can't get the formatting right to set a length for each one. I tried three sets of specifiers separated by commas but it just prints the additional specifiers. I know this is probably something really simple...

If you want to put the result in a String you can use :

String result = String.format("%-30s %-30s %-30s", divName, heading1, heading2);

Then you can print it or use it in another places

To get formatting on each of them you need to pass them separately to printf rather than combining them into one string with +.

System.out.printf("%-30s %-30s %-30s", divName, heading1, heading2);
