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 that it is to buffer input from. (You can also specify a buffer size at this time, although the default size is usually fine.) Typically you use this sort of buffering when you are using a FileReader or InputStreamReader.
BufferedReader defines the standard set of Reader methods, and also provides a readLine() method that reads a line of text (not including the line-terminators) 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.
