What is object equality in Java?

In Java, object equality refers to how two objects are compared to determine if they are considered equal. This can be done using the '==' operator or the '.equals()' method.

What's the difference between '==' and '.equals()'?

The '==' operator checks if two references point to the same object in memory, while '.equals()' checks for logical equality, meaning the content of the objects is the same.

When should I override the '.equals()' method?

You should override the '.equals()' method when you want to define a custom way to compare the contents of your objects, especially if they are used in collections.

Can you give an example of overriding '.equals()'?

Sure! Here's a simple example: in a class 'Person', you might override '.equals()' to compare based on 'name' and 'age' fields.
