Scanner vs. BufferedReader

Question

As far I know, the two most common methods of reading character-based data from a file in Java is using Scanner or BufferedReader. I also know that the BufferedReader read files efficiently by using a buffer to avoid physical disk operations. My questions are:

• Does Scanner performs as well as BufferedReader?
• Why would you choose Scanner over BufferedReader or vice versa?

Answer 1

The scanner is utilized for parsing symbols from the contents of the stream while BufferedReader just shows the stream plus does not do any specific parsing.

You can pass a BufferedReader to a scanner as the origin of characters to parse.
