Write byte array to file using BufferedOutputStream

Writing the function:

public static void writeByteArrayToFile(String fileName, byte[] byteArr)
{
    BufferedOutputStream bos = null;     
    try
    {
        //create an object of FileOutputStream
        FileOutputStream fos = new FileOutputStream(new File(strFileName));         
        //create an object of BufferedOutputStream
        bos = new BufferedOutputStream(fos);
         
                 
        /*
        * To write byte array to file use,
        * public void write(byte[] b) method of BufferedOutputStream
        * class.
        */
        System.out.println("Writing byte array to file");   
        bos.write(byteArr);         
        System.out.println("File written");
    }
    catch(FileNotFoundException fnfe)
    {
     System.out.println("Specified file not found" + fnfe);
    }
    catch(IOException ioe)
    {
      System.out.println("Error while writing file" + ioe);
    }
    finally
    {
        if(bos != null){
            try
            {             
                //flush the BufferedOutputStream
                bos.flush();                 
                //close the BufferedOutputStream
                bos.close();         
            }
            catch(Exception e){//don't swallow 
//exceptions..add your code accordingly}
        }
    }
}

Using the above function:

String fileName = "C:\demo.txt";
String str = "BufferedOutputStream Example to write byte array";
writeByteArrayToFile(fileName,str.getBytes());
