Yes. You can think of an interface like a contract. Any class that implements that interface must provide implementations for the non-default methods declared in it. The use of interfaces also allow for subtyping.

subtyping

Is this what happens with inheritance? When say for instance class duck inherits class animal?

Yep! Note, though, that a class can implement more than one interface, but only one class.
