No.
The private modifier says that no other class can see that attribute. Since interfaces cannot contain any implemented methods (no functional code), there would be no reason to allow for private members of an interface.

What is the difference between a required attributes and optional attributes?
strong entity : in this the attributes must have values for instance . weak entity : in this the attributes may or may not have values for instance .
What does oop stand for?
OOP (Object Oriented Programming) is the implementation phase of OOD. OOD (Object Oriented Design) is a philosophy that considers things as objects that have attributes and methods. There can be public attributes and methods, and there can be private attributes and methods. The public interface is used to design the relationship between the object and its users, while the private interface is used to design the implementation of how that object works. If done correctly, the private implementation can be changed without requiring any change to the public interface or to its users. Often, a new object can be defined as a derivation of some other object, such as an officer is an employee. The derivation would add the necessary public and private aspects of an officer while inheriting the prior implementation of the public and private aspects of an employee.
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.
How can access an interface from another interface and how to access from a class?
Interfaces are designed to do exactly that: to interface or to interact. In object-oriented programming languages such as C++, you can incorporate up to three different interfaces per class. The private interface is accessible only to the class itself and to friends of the class. The protected interface is the same as the private interface but is also accessible to derivatives of the class. The public interface is accessible to any code. For one interface to interact with another interface, the first must have access to the second. If the first is a friend of the second or both are members of the same class, the first has unrestricted access to the private, protected and public interfaces of the second. If the first is derived from the second but is not a friend, the first only has access to the protected and public interfaces of the second. If the first is completely separate from the second, the first only has access to the public interfaces of the second.
When you implement an interface method it should be declared as public in java?
This is not necessarily true. The only rules for this are that interface methods may not be private. They may be public, protected, or have the default (blank) access modifier.

What is the word used for characteristics of an object?
Properties. The properties of an object are defined by its attributes (data representation) and its interface (methods).
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.
Is skating a personification?
Personification is giving something without human like attributes, human like attributes. For instance giving a pen the ability to talk is personification.
How do you create an interface?
by declaring in the header of the class: public/private interface [interfaceName] and do not write any method body(i.e. public void dance();)
What will happen if a private ip address is assigned to a public interface connected to an isp?
Address in a private range will not be routed on the internet backbone
How can a base class protect derived classes so that changes to the base class will not affect them explain with example?
In order for a base class to protect derived classes, so that changes to the base class do not affect the derived classes, you must make sure that the public interface exposed by the base class does not change when the implementation of those public methods do change. You can also prevent inadvertant access to the base class attributes from the derived class, by making them private. class base { public: base(...) {...}; /* constructor */ base~(...) {...}; /* destructor */ method(...) {...}; /* other public methods */ private: ... etc. } class child : base { public: ... private: ... } So long as the calling sequence and functionality (interface) of the base class public methods do not change, the implementation of those public methods can change, and the private methods and attributes can change, without impacting any child class.
What is exteranalizable in java?
Externalizable interface is a subclass of Serializable. Java provides Externalizable interface so as to give you more control over what is being serialized and what is not. Using this interface, you can Serialize only the fields of the class you want serialize and ignore the rest. This interface defines 2 methods: readExternal() and writeExternal() and you have to implement these methods in the class that will be serialized. In these methods you'll have to write code that reads/writes only the values of the attributes you are interested in. Programs that perform serialization and deserialization have to write and read these attributes in the same sequence
