When will you define a method as static in java?
Static keyword when used with a method, specifies that this method belongs to the class and not a particular instance of the class (a.k.a object of the class) Ex: public class StaticTest { public static String getAuthorName() { return "Anand"; } } Here getAuthorName is the static method and it can be accessed without instantiating an object of the class StaticTest. You can access this method as: String authorName = StaticTest.getAuthorName();
What is an interface class and what is an abstract class?
The term interface class does not exist in C#. If this is a term describing a class being an interface to other component (human, subsystems, etc), it is very application specific. The designer of that application should know the abstraction.However, C# does have another type called interface. An interface is NOT a class. An interface defines the intention of some behaviors that classes may be extended it and provides the implementation. The intention, is nothing but method signatures, which defines the return data type, the method name, and any method arguments and associated data type. The implementation is the code of the method. Interface is used for separating the concern of design and implementation.Abstract class is a class with abstract keyword. It can be just like a class without that keyword (then, why it is an abstract class?). But it may have some methods or properties defined as abstract. These abstract methods, like the method signatures of an interface, defines the intention.The subclasses of such an abstract class would need to implement those abstract methods (providing the code).There are more common, differences between interfaces and abstract classes, please see answer(s) of those related questions in C# category.
Why cannot initialize data member within class?
A class is a type. Classes don't do anything except define the type. You have to instantiate an object of the type in order to actually do anything, including initialising data members. However, the class can define how a data member is initialised. The most efficient method of initialising class members if via the class constructor initialisation list.
What is storage class Define storage class with the help of example?
the storage class is define as 10th class and 9th class and the examples are 10b and 9a
How are data and method organised in object-oriented program Illustrate the same for car object?
For example, given a base class of "Car," polymorphism enables the programmer to define different "StartEngine" methods for any number of derived classes. The "StartEngine" method of a derived class named "DieselCar" may be completely different from the method with the same name in the base class.

What is function in java terminology?
In Java, a function is called a "method". In Java as well as other languages, a method is a function defined specifically for one class. In Java, this is the only way to define functions, therefore, all functions are methods.In Java, a function is called a "method".

In java why method defined in super class need not to defined in subclass?
In Java, or in any object oriented language such as C++, a method defined in super (parent) class does not need to be defined in a subclass, because that is the primary purpose of inheritance. Object oriented programming allows you to define and declare a class that implements the behavior for an object. Inheritance allows you to refine, or subclass, that class by "reusing" all of the functionality of the parent class into the sub class, adding additional definition and declaration for the sub class. If the subclass needs to change a parent class method, it can overload that method. This is called abstraction.
Why might you want to define an abstract class?
You would use an abstract class when you want a number of classes to have a similar functionality/methods list. The abstract class will have only method declarations and no definitions. So any class that extends this abstract class would have to provide the method definitions. This way you can ensure that all these classes will have a similar set of methods/features. This type of usage of an abstract class is similar to interfaces.
