ByteArrayInputStream skip() method in Java with Examples

The skip() method is a built-in method of the Java.io.ByteArrayInputStream which skips arg bytes in the input stream. A fewer bytes is skipped if the stream has reached towards the end.

Syntax:

public long skip(long args)

Parameters: The function accepts a single mandatory parameter args which specifies the number of bytes to be skipped

Return Value: The function returns the number of skip bytes.

Errors an Exceptions: The function throws an IOException when I/O error occurs.

Below is the implementation of the above function:

Program 1:

// Java program to implement
// the above function
import java.io.*;

public class Main {
    public static void main(String[] args) throws Exception
    {

        byte[] buf = { 5, 6, 7, 8, 9 };

        // Create new byte array input stream
        ByteArrayInputStream exam
            = new ByteArrayInputStream(buf);

        // print bytes
        System.out.println(exam.read());

        // Skips 1 element
        exam.skip(1);

        System.out.println(exam.read());
        System.out.println(exam.read());
    }
}

Output:

5
7
8

Program 2:

// Java program to implement
// the above function
import java.io.*;

public class Main {
    public static void main(String[] args) throws Exception
    {

        byte[] buf = { 1, 2, 3, 4, 5, 6, 7, 8 };

        // Create new byte array input stream
        ByteArrayInputStream exam
            = new ByteArrayInputStream(buf);

        // print bytes
        System.out.println(exam.read());

        // Skips 3 elements
        exam.skip(3);

        System.out.println(exam.read());
        System.out.println(exam.read());
    }
}

Output:

1
5
6
