# Can you tell the difference between equals() method and equality operator (==) in Java?

\

| ## equals() | **==** |
| --- | --- |
| This is a method defined in the Object class. | It is a binary operator in Java. |
| This method is used for checking the equality of contents between two objects as per the specified business logic. | This operator is used for comparing addresses (or references), i.e checks if both the objects are pointing to the same memory location. |

**Note.**\

- In the cases where the equals method is not overridden in a class, then the class uses the default implementation of the equals method that is closest to the parent class.
- Object class is considered as the parent class of all the java classes. The implementation of the equals method in the Object class uses the == operator to compare two objects. This default implementation can be overridden as per the business logic.
