BufferedReader Constructors

Constructor	Description
BufferedReader(Reader in)	Creates an object with a default-size buffer for the given character input stream in.
BufferedReader(Reader in, int size)	Creates an object with a buffer of size for the given character input stream in.

BufferedReader Methods

BufferedReader basically inherits and uses Reader methods.

Method	Description
String readLine()	Reads one line. It reads until it meets a newline character(’\n’, ‘\r’).

Using the readLine() method makes character reading more efficient. It is easier to process by reading one line at a time than by reading one character at a time with the existing read() method.
