Why abstract class used in java ?
hay friends
as we know that we can not create the instance of abstract class than why we use abstract class....

Anoop Kumarsuppose you have to write code for TwoWheeler.
Lets make a abstract class for TwoWheeler do following things in common
1. Turning mechanism
2. break mechanism
But following things can be differ from kind of TwoWheeler
A. Gear Mechanism
you can write with implementation of 1 & 2 method in abstract class and provide a abstract method for GearMechanism.
Now whatever class will extend TwoWheeler class, they already have method 1,2 and just need to implement method A. this give you proper reuse of code.
PS: In java, always think as if in real scenarios, makes java like a cake. more you eat more you get amused😀 -
