readable closeable

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 .
