DataInputStream readShort() in Java

readShort(): This method is available in the java.io.DataInputStream class of Java.

Syntax:

short java.io.DataInputStream.readShort() throws IOException

This method sees the general contract of the readShortmethod of DataInput. Bytes for this operation are read from the contained input stream.

Parameters: NA

Returns: the next two bytes of this input stream, interpreted as a signed 16-bit number.

Throws:

1. EOFException - if this input stream reaches the end before reading two bytes.

2. IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

Approach

Java

import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

public class DataInputStreamreadShort {
    public static void main(String[] args) throws IOException {

        InputStream in = new FileInputStream("hello.txt");
        DataInputStream dataInputStream = 
                        new DataInputStream(in);

        System.out.println(dataInputStream.readShort());

        dataInputStream.close();
    }
}
