Each programming language that supports these entire three features is known as the Pure-Object oriented language. Whereas if a programming language support all these three features but not support completely are known as the Partial-Object oriented languages or the Semi Object-oriented languagesThe main reasons why the C++ programming language is Known as Semi-Object oriented language are as follows:Availability of the Friend function- A friend class is allowed to access private and protected members of another class, within which it is declared a friend. It may be very useful for some time, but still, it violates the rule of the Object-Oriented features.Concept of the Global variable- As we all know that we can declare a global variable in C++ language that can be easily accessible from anywhere within the program. So again, C++ does not provide complete privacy because no one is restricted to access and manipulate that data/information. Hence it offers partial Encapsulation, unlike Java Language, in which a user only allows to declare a variable within the class and can provide access specifier to it.The main function is Out-side the class- C++ is an object-oriented language, but still, object-oriented is not fundamentally related (or implicit) to the language.

In other words, an empty interface (containing no fields and methods) is called a marker interface. In Java, the most commonly used marker interfaces are Serializable, Cloneable, Remote, and ThreadSafe interfaces. Marker interfaces are also known as the Tag interface. It is used to tell the JVM or compiler that the particular class has special behavior.Following is the code snippet of a maker interface:\r\npublic interface Cloneable \r\n{\r\n // empty \r\n}\r\nHence, the correct answer is option (b).", "source_url": "https://www.tpointtech.com/java-mcq"}

The important features of the final keyword are:Using the final keyword with a variable makes it constant or immutable. We can't reassign the values of it.A final variable must be a local variable and cannot be used in other classes.Using the final keyword with a method makes it constant, and we can't override it in the subclass.Using final with a class makes the class constant, and we cannot extend a final class.
