A whisper in my ear tells me it would do this:

indexOf(String str, int fromIndex)
          Returns the index within this string of the first occurrence of the specified substring, starting at the specified index.

So uh... probably the same thing asindexOf(0)in this case.

i believe it does something like this
api is always useful, and you can always test out the code at the interaction.

Whoa whoa whoa. Don't link him to old docs. 1.4 is much different than 1.6, though not in this case.

Here is the newest api docs:

http://java.sun.com/javase/6/docs/api/

I usually just google "java 6 whatever" where whatever is the class I'm looking for. For example:

google "java 6 String" and the first result is:

http://java.sun.com/javase/6/docs/api/java/lang/String.html

Your teacher doesn't sound like much of a programmer, at least with java. Is this highschool or college?

Tell him about javadocs. Seriously. Java isn't java without 'em.
