Question: What Is The Difference Between The Final Method And Abstract Method?

Can we declare static method as final?

Static methods are class level so there are not part of object.

So we can not override static methods but we can call super class static method using subclass name or instance also.

When we declare static method as final its prevents from method hiding..

Can we develop a static method in abstract class?

Yes, abstract class can have Static Methods. The reason for this is Static methods do not work on the instance of the class, they are directly associated with the class itself.

Can final method be overloaded?

private and final methods can be overloaded but they cannot be overridden. It means a class can have more than one private/final methods of same name but a child class cannot override the private/final methods of their base class.

Can you use abstract and final both with a method?

Declaring abstract method final But, in-case of abstract, you must override an abstract method to use it. Therefore, you cannot use abstract and final together before a method.

What is the difference between virtual method and abstract method?

Virtual methods have an implementation and provide the derived classes with the option of overriding it. Abstract methods do not provide an implementation and force the derived classes to override the method. So, abstract methods have no actual code in them, and subclasses HAVE TO override the method.

Can final method be inherited?

No, we cannot override a final method in Java. The final modifier for finalizing the implementations of classes, methods, and variables.

Can we override static method?

Can we Override static methods in java? We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism. Hence the answer is ‘No’.

Why we Cannot override static method?

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

Can you call a static method of an abstract class?

Yes, of course you can define the static method in abstract class. you can call that static method by using abstract class,or by using child class who extends the abstract class. Also you can able to call static method through child class instance/object.

Can a final class be abstract?

A final class can’t be extended, an abstract class needs to be extended in order to be instantiated. Therefore, a final abstract class would be a logical contradiction.

Can final method be overridden?

You use the final keyword in a method declaration to indicate that the method cannot be overridden by subclasses.

When abstract methods are used?

Abstract classes cannot be instantiated and are designed to be subclassed. They are used to provide some common functionality across a set of related classes while also allowing default method implementations. In this article, we’ll discuss a real world scenario for using an abstract class in Java.

Can we use virtual method in abstract class?

Answer: Yes, We can have virtual method in an Abstract class in C#. This is true that both virtual and abstract method allow derived classes to override and implement it. … If we don’t override an abstract class in derived classes compiler will flash an error.

Can final method be extended?

A final class cannot be extended. A final method cannot be overridden. A final variable cannot be assigned to after it has been initialized.

Can abstract class have static and final methods?

Yes, it can. But the final method cannot be abstract itself (other non-final methods in the same class can be).

Can abstract class have static and final variables?

An abstract class may contain non-final variables. Type of variables: Abstract class can have final, non-final, static and non-static variables. Interface has only static and final variables. … A Java abstract class can have class members like private, protected, etc.

Can we declare virtual method in abstract class?

Key things about the abstract methods: An abstract method is by default a virtual method. Abstract methods cannot be declared as static, or virtual.

Can abstract class have constructor?

Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
