Many thanks for your reply. This was implicit and is going on. But not of much help.
Can you explain to us why it didn't help? We can't elaborate on your issue if we don't know why.
And explaining what is a marker interface... etc. when the google links does a good job is just a bit silly.
As for the "business requirement" part of your question, that doesn't really make sense. The "marker interface" is a technique (or
pattern, for those who like that terminology). It may be used indirectly to solve a "business requirement", but otherwise, is unrelated.
