java BufferedReader question

Comment:
In Java, when I read a line by executing .readLine(), the pointer gets to point the begining of the next line in a stream. My question is if there is any way to go back to the begining of the previous line. Is this possible? thanks

There are two methods for this, mark() and reset()... use mark() to keep track of that particular postion in the stream, and use reset to get back to that position. I'm not sure what you have in mind, but its not quite like rolling back a transaction in the database or something like that. You have to give mark() a read-ahead limit, and if you pass that limit and try a reset, it will probably fail.
