What is BufferedReader in Java Programming?

Answer 1

BufferedReader is a class used to read text from charater-input stream and buffering characters which reads characters, arrays, and new lines.

In general, each read request made using "Reader" class, causes a corresponding read request to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders. For example, BufferedReader in = new BufferedReader(new FileReader("foo.in"));
