Java/File Input Output/BufferedOutputStream

Create BufferedOutputStream from FileOutputStream

   <source lang="java">

import java.io.BufferedOutputStream; import java.io.FileOutputStream; class BufferedOutputStreamDemo {

 public static void main(String args[]) throws Exception {
   FileOutputStream fos = new FileOutputStream(args[0]);
   BufferedOutputStream bos = new BufferedOutputStream(fos);
   // Write 12 bytes to the file
   for (int i = 0; i < 12; i++) {
     bos.write(i);
   }
   bos.close();
 }

}

 </source>
   
  
 
  

Write byte array to file using BufferedOutputStream

   <source lang="java">

import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; public class Main {

 public static void main(String[] args) throws Exception {
   FileOutputStream fos = new FileOutputStream(new File("C:/Demo"));
   BufferedOutputStream bos = new BufferedOutputStream(fos);
   bos.write("this is a test".getBytes());
   bos.flush();
   bos.close();
 }

}

 </source>
   
  
 
  

Write byte to file using BufferedOutputStream

   <source lang="java">

import java.io.BufferedOutputStream; import java.io.FileOutputStream; public class Main {

 public static void main(String[] args) throws Exception {
   FileOutputStream fos = new FileOutputStream("C:/Demo.txt");
   BufferedOutputStream bos = new BufferedOutputStream(fos);
   byte b = 66;
   // write a character represented by ascii 66 i.e. "B"
   bos.write(b);
   bos.flush();
   bos.close();
 }

}

 public static void main(String[] args) throws Exception {
   BufferedOutputStream bufferedOutput = new BufferedOutputStream(new FileOutputStream(
       "yourFile.txt"));
   bufferedOutput.write("Line one".getBytes());
   bufferedOutput.write("\n".getBytes());
   bufferedOutput.write(65);
   bufferedOutput.close();
 }
