FileOutputStream objFileStream = new FileOutputStream(file);
objFileStream.write(byteArray);
// create a file input stream to read content of the file.
FileInputStream objFin = new FileInputStream(file);
ReadFilterInputStream obj =new ReadFilterInputStream(objFin);
System.out.print("Content of the file " + file + " : ");
// read() method reads one by one element.
System.out.print((char)obj.read());
System.out.print((char)obj.read());
System.out.print((char)obj.read());
System.out.print((char)obj.read());
