What is Foo ??

[Arnaud D]

What is the term Foo ??? I see it all over the place, in most examples : setFoo() getFoo(), Foo.class , import java.foo.* ??   Is it a generic term used in examples like someone would say MyClass or myMethod ? Or am I just passing next to a very important concept ??   This might be a stupid question, but hey, like you never said anything dumb !!   Thanx for answering me, not knowing won't make me a worse programmer (?) nor an insomniac, but i don't want to die ignoring this!   Regards, Arnaud D
