According to a beginner's book on Java, an interface can't have constructors. Also, the interface itself can't contain the method implementation.
No. You can declare a dynamic array without specifying a length, but in order to physically instantiate (either by using malloc or by using object-oriented construction) you must provide a length.
Graphical User Interface
Its an interface.
No. An interface cannot implement another interface, it can only just extend it. Because, an interface cannot implement any method as it has no method body declarations.
Yes. An abstract class is a conceptual class (an incomplete class) that provides a generic interface for two or more actual classes (the derived classes). For instance, a shape is not an actual object, nor is a mammal. They are simply a type of object; a conceptual object. A square is an actual type of shape, just as a golden Labrador is a specific breed of dog, an actual mammal. The conceptual classes merely provide a generic interface to the actual object, but do not have enough information to implement that interface. For instance, all shapes can be drawn, but without knowing what type of shape to draw, the conceptual shape cannot implement the draw method, it can only provide the interface. By declaring the shape::draw method to be pure-virtual, you not only ensure that you cannot instantiate a shape by itself (it is merely an abstraction), you also ensure that all the derivatives of the shape class provide a specific implementation of that interface.
No. An interface can only be implemented.
No. You must create a subclass of the abstract class in order to be able to instantiate it.
int* pint; // instantiate a pointer to an int. float* pflt; // instantiate a pointer to a float.
The term 'instantiate' can be used in many different ways. The word 'instantiate' is a term meaning to provide an example. One way an individual might use the term is 'The mom instantiated how to tie her shoe.'

Graphical User Interface
A tagging interface type in Java is an interface that has not defined methods such as the java.io.Serializable interface.
