How can I make a copy of a BufferedReader?

Question

I am using a BufferedReader constructor to make a new copy of an existing BufferedReader.

BufferedReader buffReader = new BufferedR         


        

Answer 1

Passing in a BufferedReader instance in the constructor for a new BufferedReader will not make a copy of the original BufferedReader!

What you are doing there is chaining the two reader, in other words, you are buffering the already buffered reader instance. When you call readLine() on buffReader, it will call readLine() on originalBuffReader.
