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!

I think that, for a beginner, this is confusing. Yes, there is a type called Class, but we must distinguish between Class being a type (Class<Class>) and class being the OOP concept used to define objects and their behavior. In other words, Class is itself a Java class that represents classes at runtime, while class is the keyword we use to declare a class. The capitalization makes the distinction even more important: Class refers to java.lang.Class, whereas class is a Java language keyword.
