The class reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.Following are the important points about BufferedReader:

  • The buffer size may be specified, or the default size may be used.

  • Each read request made of a Reader causes a corresponding read request to be made of the underlying character or byte stream.

Class declaration
