String.format() throws FormatFlagsConversionMismatchException

Question

This code works fine in Java 1.6:

 public static String padLeft(String s, int n)
 {
     if (n <= 0)
         return s;
     int noOfSpaces = n * 2;
              


        

Answer 1

Since you are using # flag in format string, you should pass Formattable as an argument (doc).

Any work arounds?

Don't use # in format string?
