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

i believe it does something like <a href="http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#indexOf(int,%20int)">this</a> 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. |
