Working with BufferedReader

 BufferedReaderimproves performance by buffering input.

 It hastwo constructors:

BufferedReader(Reader InputStream)

BufferedReader(Reader InputStream, intbufSize)

The first form creates a buffered character stream using a default buffer size. In the second, the size of the buffer is passed in bufSize.

 Example:

import java.io.*;

classBufferedreader

{

public static void main(String args[]) throws IOException

 {

FileReader f=new FileReader("File1.txt");

BufferedReader b=new BufferedReader(f);

  String s;

while((s=b.readLine())!=null)

System.out.println(s);

 }

}

Output:

Hello this is written to the file using print stream

Again the next line is also written to the file
