How to Read From & Write To Files in Java

[@bangladeshibadmintonny]

I was looking for various ways we can read/write to a file to refresh my memory and you showed it all in this video, thank you. I think it'd be complete if you added the stream classes.

I am trying to use a java program to update multiple files of similar types in a directory using a field value. Could you please suggest.
