Class size to make the most of OOP

This might seem like a stupid question, Im trying to dicsuss now with you how you see on the subject and im not after a real answear. What i want is to build my own view on the following subject.

EDIT: For you who didn’t know already OOP stands for Object Oriented Programming

When is a java class becoming too big?
How many lines / methods do you try to make per class?
How do you think the above question effecrts your programming?
Do you prefer smaller or bigger classes?
Do you consider OOP be few big classes or many small classes?
Does having many small classes affect you negative?
Does having many big classes affect you negative?

Hoping to start a discussion with spread oppinions :slight_smile:
