"Hello, Amigo! Bilaabo will tell you the differences between an abstract class and an interface. There are several."
|An abstract class can inherit only one class but it can inherit any number of interfaces.||An interface cannot inherit classes, but it can inherit any number of interfaces.|
|An abstract class can contain abstract methods. But it may not have any at all.||All of an interface's non-static and non-default methods are abstract, i.e. they have no implementation. An interface can have no methods at all.|
|Methods with an implementation|
|An abstract class can contain methods with an implementation.||An interface may have default methods.|
|No restrictions.||An interface contains only public final static data.|
|You cannot create an instance of an abstract class.||You cannot create an instance of an interface.|
"That's my understanding. Brief and to the point."
