This class applies buffering to a
character input stream, thereby improving the efficiency of character
input. You create a BufferedReader by specifying
some other character input stream from
which it is to buffer input. (You can also specify a buffer size at
this time, although the default size is usually fine.) Typically, you
use this sort of buffering with a FileReader or
InputStreamReader.
BufferedReader defines the standard set of
Reader methods and provides a readLine(
) method that reads a line of text (not including the line
terminator) and returns it as a String.
BufferedReader is the character-stream analog of
BufferedInputStream. It also provides a
replacement for the deprecated readLine(
) method of
DataInputStream, which did not properly convert
bytes into characters.
