Thread: Static Method Help

I'm trying to use a static method to find out how many years it takes to double an arbitrary amount of money so I used a dummy amount of money. The problem is, the code compiles but the code does not run properly. What am I doing wrong?

class YearsToDouble
{
   public static void main ( String [] args ) throws Exception
   {
      System.out.println("rate(percent)   years to double");
      for ( int percent : new int[] {1,2,3,4,6,9,12,24} ) line(percent);
   }
   public static void line ( int percent )
   {
      System.out.printf("%7d%17d\n",percent,yearsToDouble(percent));
   }
   public static int yearsToDouble ( int percent )
   {
      double balance = 1.00;
      int years = 0;
      while ( balance < 2.00)
      {
         balance += ((percent/100)*balance);
         years++;
      }
      return years;
   }
}

Now I get it Thanks!
