It's very simple, is a id generator. A number combined with characters array. Mostly used for keys and unique IDs.

Just a little ideia in code pattern matter, I'd just change the constructor to private e make generateId a static factory (Bloch, Effective Java).
i.e.
public static Id generateId(int logitud){
Id id = new Id(longitud);
id.idArray = new String[logintud];
....
return id;
}
this helps to build more semantic sentences :D i.e. Id.generateId(10);
Just an ideia (I like to share and discuss code pattern stuff hehehe):D
Best regards!
