Constructors handle initialization. They set initial variables and you need to call one before using an object (or it will throw null pointer exceptions.)
Constructors are a pretty basic part of OOP and I recommend you read some java tutorials on this because it is something you should know. Maybe someone here can offer a more detailed explanation though.

Thanks first for the explanation you gave. It is helpful.
Are you worried specifically about constructors because you know another language that doesn't have them? Are you familiar w/ OOP?
