What are different ways to achieve polymorphism?

what are the different ways to achieve polymorphism in c++

• by using inheritance (through the use of a pointer to a base class)
• by using virtual function.
• by using abstract classes.

How is polymorphism implemented in Java?

Java implements polymorphism in two ways: 1. Static or compile-time polymorphism is done by method overloading (more then one methods sharing the same name but different number/types/order of parameters) 2. Dynamic or runtime polymorphism is done by method overriding (defining a method in the child…

How many ways can we achieve polymorphism in Java?

Polymorphism in Java can be performed by two different methods: Method Overloading. Method Overriding.

Which of the following options is not used to achieve polymorphism in Java?

Which among the following can’t be used for polymorphism? Explanation: Static member functions are not property of any object. Hence it can’t be considered for overloading/overriding. For polymorphism, function must be property of object, not only of class.

What are the benefits of polymorphism in Java?

Advantages of Polymorphism

• Programmers code can be reused via Polymorphism.
• Supports a single variable name for multiple data types.
• Reduces coupling between different functionalities.

What are the two methods used to implement polymorphism?

Polymorphism in Java has two types: Compile time polymorphism (static binding) and Runtime polymorphism (dynamic binding). Method overloading is an example of static polymorphism, while method overriding is an example of dynamic polymorphism.

What are override methods?

An override method provides a new implementation of the method inherited from a base class. The method that is overridden by an override declaration is known as the overridden base method. An override method must have the same signature as the overridden base method.

What is polymorphism give three advantages of polymorphism?

Advantages of Polymorphism It helps the programmer to reuse the codes, i.e., classes once written, tested and implemented can be reused as required. Saves a lot of time. Single variable can be used to store multiple data types. Easy to debug the codes.

How can polymorphism help you create reusable code?

It refers to something having many forms, referring to both objects and methods. Polymorphism allows you to code to an interface that reduces coupling, increases reusability, and makes your code easier to read. Performance may degrade when using polymorphism in some situations, but this doesn’t mean we should avoid it.

How do Interfaces support polymorphism in Java?

Interfaces formalize polymorphism. Interfaces allow us to define polymorphism in a declarative way, unrelated to implementation. Classes that realize the same interface may be substituted for one another in the system, thereby supporting the changing of implementations without affecting clients.

What is polymorphism in oops?

Polymorphism is a feature of object-oriented programming languages that allows a specific routine to use variables of different types at different times. Polymorphism is the ability of a programming language to present the same interface for several different underlying data types.

What is static function in Java?

Static Method Static methods are the methods in Java that can be called without creating an object of class. They are referenced by the class name itself or reference to the Object of that class.
