EASY - silly question from a beginner...

////////////////////////////////////////////////////
public class welcome {

      /**
       * @param args
       */
      public static void main(String[] args) {
            String strOne = "this is a string";

            int intOne = NumberOfBytes(strOne);
            System.out.println(strOne);
            System.out.println(intOne);
      }

}
class NumberOfBytes{
      int storage (String s){
            return s.length() * 2;
      }
}

////////////////////////////////////////////////////////
says:
the method NumberOfBytes(String) is undefined for the method welcome

why?

CEHJ

Change

>>class NumberOfBytes{

to

static class NumberOfBytes{

and

>>int intOne = NumberOfBytes(strOne);

to

int intOne = NumberOfBytes.storage(strOne);

Hurrah! Thank you CEHJ. It needs to be static, because otherwise it doesn't exist...

yay.
