Please explain me the difference between scanner and the buffer reader

Question

Hi, I have a doubt why buffer reader is safer to take user input in java?

Can you explain that to me?

Thank you,

Answer 1

1. BufferedReader is synchronous while Scanner is not. 
2. BufferedReader should be used if we are working with multiple threads.
3. BufferedReader has significantly larger buffer memory than Scanner.
4. The Scanner has a little buffer as opposed to the BufferedReader, but it’s more than enough.
5. BufferedReader is a bit faster as compared to scanner because the scanner does parsing of input data and BufferedReader simply reads a sequence of characters.

I hope this will help you to understand the difference,

Thank you

Answer 2

As per your question for reading a text file you should use BufferedReader because Scanner hides IOException while BufferedReader throws it immediately.

BufferedReader is synchronized and Scanner is not.

Scanner is used for parsing tokens from the contents of the stream.

BufferedReader just reads the stream.
