Please any explain me when to use abstract class and interface?

interface: I don’t now about anything to implement…. Then go.

abstract: I know some part of implementation then go..

But in interface some default and static method also allow

Yes

So it’s same as abstract class na..

Above answer is good for interview….Those are java 8 features
new enhancements

So that why I confused whrnto use because both have some implementations

No

Please explain me

Some times not possible to add another abstract method in the interface because of that interface lot of implemented classes are there, which will affect implemented classes, without affecting existing we can add static or default methods.

Means after application in prod at that time we use java 8 enhanced features

Without affecting other services correct?

Means classes that implements interface

If you want to add new functionality to the existing interface then use static or default methods…

in java there is no multiple inheritence we can achieve multiple inheritence through interfaces

and abstract works the same i dono why they even created them in the first place?

so if we want to have a class which containd multiple methods which can be accessed within the program we use interface class

Please use interface and abstract class approach, will solve the problem

Create interface with all abstract methoda

Implement interface with abstract class

Then provide default implementation for all the methods available in interface into abstract class

Then extend abstract class into your concrete classes

Then when you add any new methods also system cannot break without implement methods in concrete class

try this approach
