DataOutputStream Class writeShort() method

• writeShort() method is available in java.io package.
• writeShort() method is used to write the given value to the basic DataOutputStream as 2 bytes short (i.e. 16 bit) and the variable counter is plus by 2 on successful execution.
• writeShort() 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.
• writeShort() method may throw an exception at the time of writing short.
  IOException: This exception may throw while getting any input/output error.

Syntax:

    public final void writeShort(int val);

Parameter(s):

• int val – represents the integer value to be written as short to the data output stream.

Return value:

The return type of the method is void, it returns nothing.

Example:

// Java program to demonstrate the example 
// of void writeShort(int val) method 	
// of DataOutputStream

import java.io.*;

public class WriteShortOfDOS {
 public static void main(String[] args) throws Exception {
  InputStream is_stm = null;
  DataInputStream dis_stm = null;
  FileOutputStream fos_stm = null;
  DataOutputStream dos_stm = null;

  short[] s_arr = {
   132,
   122,
   111
  };
  try {
   // Instantiate FileInputStream, 
   // DataInputStream, FileOutputStream
   // and DataOutputStream 

   fos_stm = new FileOutputStream("C:\\Users\\Preeti Jain\\Desktop\\programs\\includehelp.txt");
   dos_stm = new DataOutputStream(fos_stm);

   is_stm = new FileInputStream("C:\\Users\\Preeti Jain\\Desktop\\programs\\includehelp.txt");
   dis_stm = new DataInputStream(is_stm);

   for (short val: s_arr) {
    // By using writeShort() method isto
    // write short value to the
    // DataOutputStream dos_stm
    dos_stm.writeShort(val);
   }


   // By using flush() method isto
   // flush the bytes to the basic 
   // output stream         
   dos_stm.flush();

   // Loop To Read Available Data till end
   while (dis_stm.available() > 0) {

    // By using readShort() method isto read 
    // short from dis_stm

    short val = dis_stm.readShort();
    System.out.println("dos_stm.writeShort(val): " + val);
   }
  } catch (Exception ex) {
   System.out.println(ex.toString());
  } finally {
   // To free system resources linked
   // with these streams
   if (is_stm != null)
    is_stm.close();

   if (dis_stm != null)
    dis_stm.close();

   if (dos_stm != null)
    dos_stm.close();

   if (fos_stm != null)
    fos_stm.close();
  }
 }
}

Output

dos_stm.writeShort(val): 132
dos_stm.writeShort(val): 122
dos_stm.writeShort(val): 111
