Sep 10, 2019 · The BufferedReader class of Java is used to read the stream of characters from the specified source (character-input stream). The constructor of this class accepts an InputStream object as a parameter. This class provides a method known as readLine() which reads and returns the next line from the source and returns it in String format.
BufferedReader in = new BufferedReader(new FileReader("foo.in")); will buffer the input from the specified file. Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient. java.io.BufferedReader readLine() Description : This java tutorial shows how to use the readLine() method of BufferedReader class of java.io package. This method returns a line of String which has been read by this BufferedReader. BufferedReader in = new BufferedReader(new FileReader("foo.in")); will buffer the input from the specified file.

BufferedReader(Reader in, int sz) : Creates a buffering character-input stream that uses an input buffer of the specified size. Methods: void close() : Closes the stream and releases any system resources associated with it.Once the stream has been closed, further read(), ready(), mark(), reset(), or skip() invocations will throw an IOException.
