string.indexof question

[shadowman571]

im in class and my teacher is trying to teach us how to use . length

in "somestring.indexof(0,0) what does the second 0 do? my teacher is unsure of this can any one help? a quick answer would be realy helpful

[rdrake]

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

Java:

indexOf(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:

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

lol its Mr Holmes he was my turing teacher last year

anyway he's a programmer used to tell us stories of his old work and whatnot but i hear he is HORRIBLE at java

seen him carrying around like 10 "java for dummies" books

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