Really need help fully understanding general concept!!!! Kind lost

I have watch almost all videos, but I don’t seem to understand why we need to create an object? And how do I know when I need to create it?

I don’t quite understand what is a field and encapsulation?

Can someone please help me, if you can give some small example I can run and test it will be very helpfully as well.

Thank you.

Jose,

Jeremy uses an example of a cookie cutter to explain classes and objects. Classes are a blueprint that allow us to create objects. Classes are just patterns with attributes called fields that describe the pattern. We can't really do anything with a pattern except create something with it. That something is called an object.

Going back to the cookie cutter; we know what shape it should be, but the only thing you can do with it is stamp out the shape into the cookie dough. Once we've created that object out of cookie dough, then we can do stuff with it, like throw it into the oven. The fields could be the color of the dough, or how think/ thing the dough has been rolled out; all attributes of the now stamped out cookie.
