The Java.io BufferedWriter is the class used for writing the characters into a directory or file. The buffered writer performance is little bit faster compared to other writers like writing the files or data into disk drive and in many more applications.

The Java.io BufferedWriter is similar to that buffered output stream with tiny difference that it writes stream of bytes like data related to images, where as the buffered writer writes the characters like in the text form. The main feature of this class is to write block of characters or data at a time instead of writing data character by character.In Java.io BufferedWriter class, contains one method called new line() method used to write the textual line at a time in characters.

Java.io/BufferedWriter class is declared below: Public class BufferedWriter extends Writer

From the following classes, methods are inherited the buffered writer class.

• Java.io.object
• Java.io.Writer

Usage of void close() method. [c]import java.io.BufferedWriter; import java.io.IOException; import java.io.StringWriter; public class BufferedWriter { public static void main(String[] args) throws IOException { StringWriter sw = null; BufferedWriter bw = null; try{ // creating a new string writer sw = new StringWriter(); //creating a new buffered writer bw = new BufferedWriter(sw); // To append character. bw.append("1"); // To close the writer bw.close(); // print before going to appending one more character System.out.println(sw.getBuffer()); // appending after closing which will throw error bw.append("2"); // print after going to appending one more character System.out.println(sw.getBuffer()); }catch(IOException e) { // if I/O error occurs System.out.print("not append, buffered writer is closed"); }finally { // releases all the system resources associated with this stream if(sw!=null) sw.close(); if(bw!=null) bw.close(); } } }[/c] Output Following is the result will be displayed. [c]not append, buffered writer is closed[/c] Usage of void flush() method. [c]import java.io.BufferedWriter; import java.io.IOException; import java.io.StringWriter; public class BufferedWriter { public static void main(String[] args) throws IOException { StringWriter sw = null; BufferedWriter bw = null; String letters = "ABCDEFG"; try{ // creating a new string writer sw = new StringWriter(); //creating a new buffered writer bw = new BufferedWriter(sw); // Represents each character in the string for (char c: letters.toCharArray()) { // To append character to the writer bw.append(c); // flush the characters to the considered stream bw.flush(); // It prints string buffer from string writer System.out.println(sw.getBuffer()); } }catch(IOException e) { // if I/O error occurs e.printStackTrace(); }finally { // releases all the system resources associated with this stream if(sw!=null) sw.close(); if(bw!=null) bw.close(); } } }[/c] Output Following is the result will be displayed. [c] A AB ABC ABCD ABCDE ABCDEF ABCDEFG[/c]
