Quick Answer: Which Definition Best Describes The Concept Of Polymorphism?

What is the definition of polymorphism?

: the quality or state of existing in or assuming different forms: such as.

a(1) : existence of a species in several forms independent of the variations of sex.

(2) : existence of a gene in several allelic forms also : a variation in a specific DNA sequence..

What is the purpose of polymorphism?

Polymorphism allows us to perform a single action in different ways. In other words, polymorphism allows you to define one interface and have multiple implementations. The word “poly” means many and “morphs” means forms, So it means many forms.

Is polymorphism and overriding same?

Overriding is when you call a method on an object and the method in the subclass with the same signature as the one in the superclass is called. Polymorphism is where you are not sure of the objects type at runtime and the most specific method is called.

What are the different types of polymorphism?

There are two major types of polymorphisms in Object Oriented Programming (OOPS) languages. They are Static Binding (Compile time Polymorphism) and Dynamic Binding (Runtime Polymorphism). Method overriding would be the example of Dynamic Polymorphism and Method Overloading would be the example of Static Polymorphism.

What is genetic polymorphism in humans?

Polymorphism involves one of two or more variants of a particular DNA sequence. The most common type of polymorphism involves variation at a single base pair. Polymorphisms can also be much larger in size and involve long stretches of DNA.

Which definition best describes the concept of polymorphism Mcq?

Which among the following best describes polymorphism? Explanation: It is actually the ability for a message / data to be processed in more than one form. The word polymorphism indicates many-forms. So if a single entity takes more than one form, it is known as polymorphism.

Why do we need runtime polymorphism?

The good reason for why Polymorphism is need in java is because the concept is extensively used in implementing inheritance.It plays an important role in allowing objects having different internal structures to share the same external interface. polymorphism as stated clear by itself, a one which mapped for many.

What is the biggest reason for the use of polymorphism?

It allows for the implementation of elegant software that is well designed and easily modified. 2. What is the biggest reason for the use of polymorphism? Explanation: Polymorphism allows for the implementation of elegant software.

What is polymorphism and example?

The word ‘polymorphism’ literally means ‘a state of having many shapes’ or ‘the capacity to take on different forms’. … An important example of polymorphism is how a parent class refers to a child class object. In fact, any object that satisfies more than one IS-A relationship is polymorphic in nature.

Why do we use polymorphism?

Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. … It is important to know that the only possible way to access an object is through a reference variable.

What is the concept of polymorphism in C++?

Polymorphism means “many forms”, and it occurs when we have many classes that are related to each other by inheritance. Like we specified in the previous chapter; Inheritance lets us inherit attributes and methods from another class. Polymorphism uses those methods to perform different tasks.

Is polymorphism good or bad?

Polymorphism (or inheritance) can lead to problems if your hierarchy becomes too big. … You could try to implement both hierarchies using virtual inheritance but this quickly leads to lots of problems (one of it is also called the “diamond problem”). Using interfaces can solve many of these problems, but at a cost.

What is an example of polymorphism in humans?

Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar’s skin colouring; they can be light morph or dark morph.

What is dynamic polymorphism?

Dynamic polymorphism is a process in which a call to an overridden method is resolved at runtime, thats why it is called runtime polymorphism. I have already discussed method overriding in detail in a separate tutorial, refer it: Method Overriding in Java.
