Zero-Padding

Posted by Matt Gerrans on November 15, 2001 at 5:49 PM

Try something like this:

public class Xero
{  
   public static void main(String[] args)
   {
      for( int i = 0; i < 20; i++ )
         System.out.println( ZeroPad(i, 2) );
   }
   static String ZeroPad( int number, int width )
   {
      StringBuffer result = new StringBuffer("");
      for( int i = 0; i < width-Integer.toString(number).length(); i++ )
         result.append( "0" );
      result.append( Integer.toString(number) );
      return result.toString();
   }
}
