The simple diffrence is abstract class can contain both abstract methods and concrete methods while interface only contains abstract methods.

Now we can declared non abstract method into interface from 1.8 later version

ajaypanchal

To declare Interface will use keyword “Interface ”.
To declare abstract will use keyword “abstract”.

==> Method: Interface contain only abstract methods while abstract class can contain both abstract methods and concrete methods

==> Constructor :-interface will not have constructors while abstract have constructors.

==> object:- we cannot create object for both interface and abstract class

==> Implement:- one Interface cannot implement another interface. While abstract class can implement another abstract class

==> Extends :- one Interface can extends another interface.

We can achieve 100% abstraction using interface keywords but we cannot achieve 100% abstraction using abstract keywords.

When we put abstract keywords in method as well as class, than it become 100% abstract class
