What is the difference between inheritance encapsulation and polymorphism?
Inheritance has to do with methods and functions inheriting the attributes of another class. Polymorphism allows program code to have different meaning or functions while encapsulation is the process of keeping classes private so they cannot be modified by external codes.
What is inheritance how it relates to polymorphism?
Inheritance refers to using the structure and behavior of a super class in a subclass. Polymorphism refers to changing the behavior of a super class in the subclass.
What is the difference between polymorphism and overriding?
3 Answers. 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 is the difference between polymorphism and abstraction?
Abstraction refers to no specific detail of something, and Polymorphism refers to methods of different objects have the same, but do different task.
Does polymorphism require inheritance?
strong type checking imposed at compile time means that all polymorphism has to come through inheritance. this leads to problems with deep inheritance hierarchies and multiple inheritance where there are all kinds of problems with unexpected side effects.
What is inheritance with example?
Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of his/her parents. With inheritance, we can reuse the fields and methods of the existing class.
Where is overloading and Overriding used?
Method overloading is used to increase the readability of the program. Method overriding is used to provide the specific implementation of the method that is already provided by its super class.
What is polymorphism used for?
In the programming world, polymorphism is used to make applications more modular and extensible. Instead of messy conditional statements describing different courses of action, you create interchangeable objects that you select based on your needs. That is the basic goal of polymorphism.
