Write byte to file using BufferedOutputStream

 

public static void writeByte2File(byte b, String fileName)
{
BufferedOutputStream bos = null;

try
{
//Create FileOutputStream for the file
FileOutputStream fos = new FileOutputStream(fileName);
//Create BufferedOutputStream object
//for FileOutputStream

bos = new BufferedOutputStream(fos);

/*
* To write a byte to BufferedOutputStream use,
* public void write(int b) method of BufferedOutputStream
* class.
*
* This method may throw IOException if something goes
* wrong.
*/

System.out.println("BufferedOutputStream: writing file");

bos.write(b);

System.out.println("BufferedOutputStream : written file");
}
catch(FileNotFoundException fnfe)
{
System.out.println("Specified file not found" + fnfe);
}
catch(IOException ioe)
{
System.out.println("Error while writing to file" + ioe);
}
finally
{
try
{
if(bos != null)
{
bos.flush();
bos.close();
}

}
catch(Exception e){}

}
}



Eg. of calling function:


String fileName="C:\demo.txt";
byte b = 65;
//this will write a character represented by ascii 65
//i.e. 'A'
writeByte2File(b,fileName);
