Java.io.RandomAccessFile.readUnsignedShort() Method

Description

The java.io.RandomAccessFile.readUnsignedShort() method reads an unsigned 16-bit number from this file. This method reads two bytes from the file, starting at the current file pointer.

Declaration

Following is the declaration for java.io.RandomAccessFile.readUnsignedShort() method

public final int readUnsignedShort()

Parameters

• NA

Return Value

This method returns the next two bytes of this file, interpreted as an unsigned 16-bit integer.

Exception

• IOException − if an I/O error occurs.

• EOFException − if this file reaches the end before reading two bytes.

Example

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

package com.tutorialspoint;

import java.io.*;

public class RandomAccessFileDemo {
   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);

         // print the short
         System.out.println("" + raf.readUnsignedShort());

         // set the file pointer at 7 position
         raf.seek(7);

         // print the short
         System.out.println("" + raf.readUnsignedShort());
      } 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:
