Suppose we have two classes

Bank in 90's

Bank in 20's

00:46

1.Add money

00:47

2.Withdraw money

00:48

3.Take loan

00:49

4.Display account details

00:50

Suppose we have written code for these features

00:50

Banks in 20's will also have features which were in 90's

5.Online money transfer

00:52

6.Online pay cheque

00:53

7.Use of debit/credit cards

00:54

So we have to write thousand lines of code which was in 90's

00:58

But this is not the ideal way

00:60

since it will take a lot of time

01:02

Here we can use Inhertitance

01:03

We will connect two classes

01:04

So that Bank's in 20's 

01:05

can access Bank's in 90's features

01:06

Suppose we made two classes

01:07

Suppose we have written code for these features

4.Display account details

3.Take loan

2.Withdraw money

01:07

Banks in 20's also have features which were in 90's

01:07

Bank in 20's

01:10

Since we are connecting two classes we don't need to write this code again

01:13

Suppose we made two classes

Bank in 90's

Suppose we have written code for these features

Bank in 20's

01:14

This is called as Base class or Parent class

01:14

Connected

01:15

This is called as Derived class

01:17

Objects of derived class
