What is the hasnext method?
Iterator.hasNext() is one of the two main methods of the Iterator interface. It can be used on an Iterator to find out if there are any remaining objects to iterate over. For example, it would be used like this: Iterator iter = ...; while (iter.hasNext()) { // do something with iter.next()... }
What are the various functions in iterator class in java?
There are mainly three Methods available in the iterator class in java. Namely they are ... 1. Has Next 2. Next and 3. Remove.
Is interface class a valid term?
Yes. An interface in essence is a java class and so you can use the term interface class. But, using the term class along with the term interface can cause ambiguity or misunderstandings among novice java developers. So, using the term "Interface" along would suffice to refer to a type of class which is the "Interface"
What is similarities between Abstract Class and Interface?
If a class has one abstract method ,the class has to be an abstract class.Methods can be implemented in abstract class.Whereas a interface is like a abstract class...the only difference being that the methods are never implemented in Interface.
What do you mean by inheriting the interface?
In object oriented programming, a derived class inherits the protected and public members of its base class. Those members therefore define the interface that is inherited by the derived class. The derived class may augment that interface to provide a more specialised implementation of the interface, without the need to re-write the generic interface of the base class. The implication is that the derived class is a more specialised form of the base class.

Why instance in abstract or interface?
we can make object of interface but in abstract we can not make object of it interface ab= new Classs(): in interface we maintain multiple inhetence by use of obj of interface we if inherit two class have same fun then we give the name of that interface and call the pertucular that fun interface ab= new class() ab.add(); but in Astract Class we cannot make object of it only class class wich inherit it can make object class ab2= new Class(); and by obj we call function of drived class ob2.add();
Interface can be defined inside another class?
yes ,interface can be defined inside another class

Can a class write inside an interface?
Yes, you can create a static class inside an interface, but it is normally not a good idea.
When you define a c plus plus class what items are considered part of the interface?
The interface of a C++ class is the public methods and attributes that are exposed by the class. In a pure abstract base class, the interface is enforced by the compiler in each of the derived child classes.
What is the latent function of friends?
The only function of a friend is to extend the private class interface outwith the class, essentially making the friend part of the class interface.
Can interface have inner class?
Yes
What is the major difference between an Interface and a Class?
An interface can only have abstract methods or constants in it. A class can have both that and everything else in Java.
