Why need PrintWriter?

Question

I am really confused about the purpose of various io classes, for example, If we have BufferedWriter, why we need a PrintWriter?

BufferedReader reader = new Buff         


        

Answer 1

The main reason to use the PrintWriter is to get access to the printXXX methods (like println(int)). You can essentially use a PrintWriter to write to a file just like you would use System.out to write to the console.

A BufferedWriter is an efficient way to write to a file (or anything else) as it will buffer the characters in Java memory before writing to the file.
