Explanation / Answer

Every value in java must be initialized before using hence in your programe variable already_counted must be initialized first.

You may think that you have initialized already_counted. but that was done in if condition. What if if condition won't be executed. That is why java describes it as a compiler error.

And there is another error at else condition. I think else is used out of blocks means without Ifs.

Thank you.

Hope you can get the solution now.
