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 −
