   public static void main(String[] args) {
   
      try {
      
         // create a new RandomAccessFile with filename test
         RandomAccessFile raf = new RandomAccessFile("c:/test.txt", "rw");

         // write something in the file
         raf.writeUTF("Hello World");

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

         // read and print the contents of the file
         System.out.println("" + raf.readUTF());

         // close the strea and release resources
         System.out.println("Closing Stream...");
         raf.close();
         System.out.println("Stream Closed.");

      } catch (IOException ex) {
         ex.printStackTrace();
      }
   }

ABCDE  

Let us compile and run the above program, this will produce the following result −

Hello World
Closing Stream...
