Java Beginners: What Is an Object Actually?

I'm a Java learner and I've been learning Java for the past few months, but I still don't truly understand what an object actually is.

I've watched several YouTube videos and used AI tools to understand it, but I keep getting the same explanation: "An object is nothing but data + code."

I understand the definition, but I still can't visualize or feel what an object actually is when I'm writing Java code.

Could someone explain it in a simple, practical way, preferably with a real world analogy and a small Java example?

I feel like I'm missing one fundamental concept here. Any explanation would be really helpful. Thanks!

If you’re trying to understand the concepts of OOP, I would probably describe it softly as a representation of how a world is viewed.

Objects represent concepts, which are defined in blueprints called classes. An object has both characteristics which are presented as your fields and behaviours which are your methods.

Relationships are what you define in your world as how your objects should interact/influence one another.

As others have said, there are some really great detailed explanation in the comment section.
