Hi,
Since interfaces variable are by default static and final.Can we assign a new value to the version variable in MediaReader class?

[admin]

You cannot change a final variable. So no, it is not possible to change version variable of Classic interface.
But MediaReader is not doing that. It has its own version variable.

Got it.Thank you.

Why not we can have option 2 (Classic).version as it will call the classic version. With option 3 (Classic.this).version should call the version of MediaReader class as we are using this which takes current class reference. Please clarify.

[admin]

Option 2 is (Classic)version; There is no dot. version is an int variable. How can you cast it to anything??

(Classic).version; is syntactically incorrect code.
