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 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

CAN ACCESS
