RandomAccessFile Class readShort() method

• readShort() method is available in java.io package.
• readShort() method is used to read signed 16-bit short integer value from this RandomAccessFile.
• readShort() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• readShort() method may throw an exception at the time of reading short integer value.
  • IOException: This exception may throw an exception while performing input/output operation.
  • EOFException: This exception may throw when the file pointer reaches EOF (End-Of-File) before reading 2 bytes.

Syntax:

    public final short readShort();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of this method is short, it returns the 2 bytes of data from this RandomAccessFile manipulated as a short integer value.

Example:

// Java program to demonstrate the example 
// of short readShort() method of
// RandomAccessFile

import java.io.*;

class RAFReadShort
public static void main(String[] args) throws Exception {
 // Instantiate a random access file
 // object with file name and permissions
 RandomAccessFile ra_f = new RandomAccessFile("e:/includehelp.txt", "rw");

 // By using writeShort() method is to 
 // write short to the file
 ra_f.writeShort(10204);

 // Initially set the file pointer
 // is at 1 for reading the file
 ra_f.seek(1);

 // By using readShort() method is to 
 // read a short value up to signed 16 bit
 // from this file

 short s = ra_f.readShort();
 System.out.println("ra_f.readShort(): " + s);

 // By using close() method isto
 // close this stream ran_f
 ra_f.close();
}
}

Output

ra_f.readShort(): -9216
