DataInputStream readUnsignedShort() method in Java with Examples

Last Updated : 05 Jun, 2020

The

readUnsignedShort()

method of

DataInputStream

class in Java is used to read two input bytes and returns an integer value. This method reads the next two bytes from the input stream and interprets it into integer type and returns.

Syntax:

public final int readUnsignedShort()
                 throws IOException

Specified By:

This method is specified by the readUnsignedShort() method of

DataInput

interface.

Parameters:

This method does not accept any parameter.

Return value:

This method returns the integer value interpreted by the next two bytes of the input stream.

Exceptions:

EOFException - It throws EOFException if the input stream is ended before two bytes can be read.
IOException - This method throws IOException if the stream is closed or some other I/O error occurs.

Below programs illustrate readUnsignedShort() method in DataInputStream class in IO package:

Program 1:

Assume the existence of file "demo.txt".

Java


 // Java program to illustrate
// DataInputStream readUnsignedShort() method
import java.io.*;
public class GFG {
    public static void main(String[] args)
        throws IOException
    {

        // Create short array
        short[] buf = { 10, 20, 30, 40, 50 };

        // Create file output stream
        FileOutputStream outputStream
            = new FileOutputStream("c:\\demo.txt");

        // Create data output stream
        DataOutputStream dataOutputStr
            = new DataOutputStream(outputStream);

        for (short b : buf) {
            // Write short value to
            // the dataOutputStream
            dataOutputStr.writeShort(b);
        }

        dataOutputStr.flush();

        // Create file input stream
        FileInputStream inputStream
            = new FileInputStream("c:\\demo.txt");

        // Create data input stream
        DataInputStream dataInputStr
            = new DataInputStream(inputStream);

        while (dataInputStr.available() > 0) {
            // Print short values
            System.out.println(
                dataInputStr.readSignedShort());
        }
    }
}

Output: Program 2:

Assume the existence of file "demo.txt".

Java


 // Java program to illustrate
// DataInputStream readUnsignedShort() method
import java.io.*;
public class GFG {
    public static void main(String[] args)
        throws IOException
    {

        // Create short array
        short[] buf = { 191, 225, 480, 763, 500 };

        // Create file output stream
        FileOutputStream outputStream
            = new FileOutputStream("c:\\demo.txt");

        // Create data output stream
        DataOutputStream dataOutputStr
            = new DataOutputStream(outputStream);

        for (short b : buf) {
            // Write short value to
            // the dataOutputStream
            dataOutputStr.writeShort(b);
        }

        dataOutputStr.flush();

        // Create file input stream
        FileInputStream inputStream
            = new FileInputStream("c:\\demo.txt");

        // Create data input stream
        DataInputStream dataInputStr
            = new DataInputStream(inputStream);

        while (dataInputStr.available() > 0) {
            // Print short values
            System.out.println(
                dataInputStr.readUnsignedShort());
        }
    }
}
