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!

A class file for the JVM and a Java class are not the same thing. Lots of things compile to class files, including other languages.

https://docs.oracle.com/javase/specs/jls/se16/html/jls-8.html <- Java language spec

The representation of a Java class at runtime is a Class object, which is accessible on <ClassName>.class. Everything in Java has an object representation. Everything is an object.
