what if we declare pi at 26th line instead of 29th line in Dog class but not in the methods .
please suggest something .

[skavyapradeep]

Everything explained nicely. But what is the difference between abstract class and interface?

[vishalpoudel]

how are abstract methods helping because we have to write it again in child class to use it same code and with a method body this time .
If we have to write that thing again why should we make abstract method i cannot understand that ??

[makemoneyeasier]

My Question is why the variable is final in interface.

[pravindeore]

You don't need to declare methods inside interface as abstract.
