ObjectInputStream Class readShort() method

• readShort() method is available in java.io package.
• readShort() method is used to read 2 bytes of short value from this ObjectInputStream.
• 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.
  IOException: This exception may throw when getting any input/output error while performing.

Syntax:

    public short readShort();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is short, it returns the 2 bytes (i.e. 16 bit) short read.

Example:

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

import java.io.*;

public class ReadShortOfOIS {
 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 readShort() method is to read
   // short from the obj_in_stm
   short val = (short) obj_in_stm.readShort();
   System.out.println("obj_in_stm.readShort(): " + 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.readShort(): 124
obj_in_stm.readShort(): 131
obj_in_stm.readShort(): 182
obj_in_stm.readShort(): 154
