         // write something in the file
         raf.writeInt(123);

         // set the file pointer at 0 position
         raf.seek(0);

         // print the int
         System.out.println(raf.readInt());

         // set the file pointer at 0 position
         raf.seek(0);

         // write something in the file
         raf.writeInt(i);

         // set the file pointer at 0 position
         raf.seek(0);

         // print the int
         System.out.println(raf.readInt());
         raf.close();
