ByteArrayInputStream Class skip() method

  • skip() method is available in java.util package.
  • skip() method is used to skip the given number of bytes (no_of_bytes) from this stream.
  • skip() 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.
  • skip() method does not throw an exception at the time of skipping bytes.

Syntax:

    public void skip();

Parameter(s):

  • long no_of_bytes – represents the number of bytes to skip.

Return value:

The return type of the method is long, it returns the exact number of bytes to be skipped.

Example:

// Java program to demonstrate the example 
// of long skip(long no_of_bytes) method of
// ByteArrayInputStream

import java.io.*;

public class SkipBAIS {
    public static void main(String[] args) throws Exception {
        byte[] by = {
            97,
            98,
            98,
            99,
            100
        };

        // Instantiates ByteArrayInputStream 
        ByteArrayInputStream byte_s = new ByteArrayInputStream(by);

        // By using available() method is to
        // return the no. of bytes to be left 
        // for reading
        Integer n_byte = byte_s.available();
        System.out.println("Left avail bytes = " + n_byte);

        // Read character from the stream
        char ch1 = (char) byte_s.read();
        char ch2 = (char) byte_s.read();
        char ch3 = (char) byte_s.read();

        // Display values
        System.out.println("ch1: " + ch1);
        System.out.println("ch2 : " + ch2);
        System.out.println("ch3: " + ch3);

        // It skip 1 bytes of data
        // from the stream  
        byte_s.skip(1);

        char ch = (char) byte_s.read();
        System.out.println("ch: " + ch);
        byte_s.close();
    }
}

Output

Left avail bytes = 5
ch1: a
ch2 : b
ch3: b
ch: d
