[@syedhabeebuddin101]

Thanks

[@hearthackermohan5704]

To achive abstract by using interface

[@abhishekgowda7383]

Constructor can't be inherited right?

[@hearthackermohan5704]

Method overriding inheritance method of super class changing implementation for sub class specification to call as method overriding best example for run time polymorphism
Method signature shoud be Same
If try to change method it act has a method overloading
Its dynamic bilding

[@poojadalve5245]

Thanks sir

[@TheKiranAcademy]

So nice of you

[@anandch3876]

after seeing all the interview i have felt like lucky because of iam non it student 😂😂🙏

[@hearthackermohan5704]

Method overloading means in a class two or more method name but different parameters and different length uis known has method overloading
Best example of method overloading compile time polymorphism
