Interfaces default to inherit from Object class in Java?

Question

Java

Hello!
I just started learning Java 8 and I had this question: Is the
interface inherited from the Object class by default or not?
If yes, for what purpose? You cannot create an instance of a class from an interface.
If not, then why is it said that everything is an object except primitive types?
Thanks in advance!

Answer 1

With this type of reference, you can call Object methods on the object, such as toString or hashCode.
So technically yes, it is inherited.
At a minimum, this allows such references to be stored in collections.

Answer 2

Interfaces in Java do not inherit from Object.
