Example

The following example shows the usage of java.io.RandomAccessFile.writeShort() method.

package com.tutorialspoint;

import java.io.*;

public class RandomAccessFileDemo {

   public static void main(String[] args) {
      try {
         short s = 15;

         // create a new RandomAccessFile with filename test
         RandomAccessFile raf = new RandomAccessFile("c:/test.txt", "rw");

         // write a short in the file
         raf.writeShort(s);

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

         // read short
         System.out.println("" + raf.readShort());

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

         // write a short at the start
         raf.writeShort(20);

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

         // read short
         System.out.println("" + raf.readShort());
      } catch (IOException ex) {
         ex.printStackTrace();
      }

   }
}

Assuming we have a text file c:/test.txt, which has the following content. This file will be used as an input for our example program:

ABCDE  

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

15
20
