Minecraft bukkit scheduler and procedural instance naming

Minecraft bukkit scheduler and procedural instance naming

This question is probably pretty obvious to any person who knows how to
use Bukkit properly, and I'm sorry if I missed a solution in the others,
but this is really kicking my ass and I don't know what else to do, the
tutorials have been utterly useless. There are really 2 things that I need
help doing:
I need to learn how to create an indefinite number of instances of an
object. I figure it'd be like this:
int num = 0;
public void create(){
String name = chocolate + num;
Thingy name = new Thingy();
}
So you see what I'm saying? I need to basically change the name that is
given to each new instance so that it doesn't overwrite the last one when
created. I swear I've looked everywhere, I've asked my Java professor and
I can't get any answers.
2: I need to learn how to use the stupid scheduler, and I can't understand
anything so far. Basically, when an event is detected, 2 things are
called: one method which activates instantly, and one which needs to be
given a 5 second delay, then called. The code is like this:
public onEvent(event e){
Thingy thing = new Thingy();
thing.method1();
thing.doOnDelay(method2(), 100 ticks);
}
Once again, I apologize if I am not giving too many specifics, but I
cannot FOR THE LIFE OF ME find anything about the Bukkit event scheduler
that I can understand.
DO NOT leave me links to the Bukkit official tutorials, I cannot
understand them at all and it'll be a waste of an answer. I need somebody
who can help me, I am a starting plugin writer.
I've had Programming I and II with focus in Java, so many basic things I
know, I just need Bukkit-specific help for the second one.
The first one has had me confused since I started programming.
Thank you in advance for any help!
