// Java program to demonstrate the example 
// of void close() method of RandomAccessFile

class RAFClose {
 public static void main(String[] args) throws Exception {
  String str = "Welcome, in Java World!!!";

  // Instantiate a random access file
  // object with file name and permissions
  RandomAccessFile ra_f = new RandomAccessFile("e:/includehelp.txt", "rw");

  // By using writeUTF() method is to 
  // write a string value to the file by using
  // UTF encoding scheme

  // by using seek() method is to 
  // set the current file indicator
  // from where read/write could 
  // start i.e. we set here 0 so reading
  // will be done from 0 till EOF;

  System.out.println("ra_f.readUTF(): " + ra_f.readUTF());

  // By using close() method isto
  // close this stream ran_f


ra_f.readUTF(): Welcome, in Java World!!!
