Can you create instances of types that are defined as an interface?
You cannot create instances of a Java interface by itself. You must always create an instance of some class that implements the interface, and reference that instance as an instance of the interface.Click to see full answer.

You cannot create instances of a Java interface by itself. You must always create an instance of some class that implements the interface, and reference that instance as an instance of the interface.Click to see full answer. In this regard, is it possible to create an instance of an interface?No, you cannot create an instance of an interface, nor can you create an instance of an abstract class. I.e., you cannot use the new keyword with an interface or abstract class. Interfaces do not have constructors.Likewise, what is an interface type? An interface type is an abstract tagged type that provides a restricted form of multiple inheritance. A tagged type, task type, or protected type may have one or more interface types as ancestors. In this regard, can an interface be used as a type? Using an Interface as a Type. When you define a new interface, you are defining a new reference data type. You can use interface names anywhere you can use any other data type name. When they implement Relatable , they can be of both their own class (or superclass) type and a Relatable type.What is the use of interface?It is used to achieve total abstraction. Since java does not support multiple inheritance in case of class, but by using interface it can achieve multiple inheritance . It is also used to achieve loose coupling.
