What is Inheritance? - When a "class" procures the property of another class it is known as Inheritance. For instance, a kid acquires the attributes of guardians.

What is Polymorphism?- While Polymorphism implies one name yet many structures. For instance, you have a cell phone for correspondence. The correspondence mode you pick could be anything. It can be a call, a content msg, a photo msg, mail, and so forth. So the objective is regular that is correspondence, yet their approach is distinctive. This is called Polymorphism. Consider a similar keeping money application.We should open two diverse record sorts, one for sparing and another for checking (otherwise called current).Let's analyze and concentrate how we can approach coding from an organized and question arranged programing point of view.

Basic approach: In organized programing, we will make two capacities –

One to pull back And the other for store activity. Since the working of these capacities stays same over the accounts.OOP's approach: While utilizing the OOPs programming approach. We would make two classes.Each having usage of the store and pull back functions.This will repetitive additional work.

Presently there is an adjustment in the prerequisite determination for something that is so normal in the product business. You should include usefulness special Banking Account with Overdraft Facility. For a foundation, overdraft is that you can pull back a sum more than accessible the adjust in your record. Utilizing utilitarian approach, I need to alter my pull back capacity, which is as of now tried and baselined. What's more, include a strategy like beneath will deal with new prerequisites. Utilizing OOP's approach, you simply need to compose new classes with exceptional usage of pull back capacity. We never touched the tried bit of code. Imagine a scenario where the necessity changes promote. Like to include Visa account with its own particular extraordinary prerequisite of stores. Utilizing basic approach you need to change tried bit of store code once more. Be that as it may, utilizing object-arranged approach, you will simply make another class with its one of a kind execution of store technique (highlighted red in the picture below).So despite the fact that the basic programming appears like a simple approach at first, OOP's wins in a long haul. However, one may contend that over all classes, you have a rehashed bit of code.

To defeat this, you make a parent class, say "record" and actualize a similar capacity of store and pull back. What's more, make youngster classes acquired "record" class. So they will have admittance to pull back and store works in record class.

The capacities are not required to be actualized exclusively. This is Inheritance in java .But hold up there is an issue! Pull back strategy for advantaged and store for a Visa is distinctive.

To beat this, you can overwrite the technique usage in your base (kid) class. To such an extent that when the "pulled back" technique for sparing record is called strategy from parent account class is executed. However, when the "Pull back" strategies for the special record (overdraft office) is called pull back strategy characterized in the favored class is executed. This is Polymorphism.
