Is my implementation correct? How to call display method from adapter class?

Answer 1

In that case , what benifit I am getting here ? I had X1 which I passed to the adapter and unnecessarily created adapter object.

This object again calls display1 from X1 only.... What is benifit of adapter pattern ?

Answer 2

Another concern is related to compatibility between two class... XML export and text export is not compatible with each other

That's why I created adapter pattern. Now it makes it compatible as per the definition of adapter pattern , but how to make int and string conversation as both class has different data types for member variables
