java.io.BufferedWriter Example in Java

By Arvind Rai, September 27, 2013

java.io.BufferedWriter writes text to character output stream. BufferedWriter buffers the writing text so that it can write efficiently to a file or any other output stream source. The buffered size can be limit by specifying the size. BufferedWriter gives greater performance in writing text. In my example I have taken a string and using BufferedWriter, I have written it to a file.

BufferedWriterTest.java

package com.concretepage.io;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
public class BufferedWriterTest {
    public static void main(String[] args) {
        File file = new File("C:\\test.txt");
        String str = "Hello World! \nThis is BufferedReader Program.";
        BufferedWriter bw = null;
        try {
          Writer w = new OutputStreamWriter(new FileOutputStream(file));  
          bw = new BufferedWriter(w);
          bw.write(str);
        } catch (IOException e) {
           e.printStackTrace();
        }finally {
            try {
                bw.close();
              } catch (IOException ex) {
                ex.printStackTrace();
              }
         }
        System.out.println("Done");
    }
}
