ObjectInputStream Class readUnsignedShort() method

• readUnsignedShort() method is available in java.io package.
• readUnsignedShort() method is used to read 2 bytes (i.e. 16 bit) unsigned short of data from the ObjectInputStream.
• readUnsignedShort() 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.
• readUnsignedShort() method may throw an exception at the time of reading unsigned short.
  • IOException: This exception may throw when getting any input/output error while performing.
  • EOFException: This exception may throw when this stream is reached its end.

Syntax:

    public int readUnsignedShort();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is int, it returns the unsigned short read.

Example:

// Java program to demonstrate the example 
// of int readUnsignedShort() method of 
// ObjectInputStream

import java.io.*;

public class ReadUnsingedShortOfOIS {
 public static void main(String[] args) throws Exception {
  // Instantiates ObjectOutputStream , ObjectInputStream 
  // FileInputStream and FileOutputStream
  FileOutputStream file_out_stm = new FileOutputStream("D:\\includehelp.txt");
  ObjectOutputStream obj_out_stm = new ObjectOutputStream(file_out_stm);
  FileInputStream file_in_stm = new FileInputStream("D:\\includehelp.txt");
  ObjectInputStream obj_in_stm = new ObjectInputStream(file_in_stm);


  // By using writeShort() method is to write
  // short to the obj_out_stm stream
  obj_out_stm.writeShort(-124);
  obj_out_stm.writeShort(131);
  obj_out_stm.writeShort(-182);
  obj_out_stm.writeShort(154);

  obj_out_stm.flush();

  while (obj_in_stm.available() > 0) {
   // By using readUnsingedShort() method is to read
   // unsigned short from the obj_in_stm and returned
   // as an integer
   int val = (int) obj_in_stm.readUnsignedShort();
   System.out.println("obj_in_stm.readUnsignedShort(): " + val);
  }

  // By using close() method is to 
  // close all the streams 
  file_in_stm.close();
  file_out_stm.close();
  obj_in_stm.close();
  obj_out_stm.close();
 }
}

Output

obj_in_stm.readUnsignedShort(): 65412
obj_in_stm.readUnsignedShort(): 131
obj_in_stm.readUnsignedShort(): 65354
obj_in_stm.readUnsignedShort(): 154
