BufferedInputStream Class skip() method

• skip() method is available in java.io package.
• skip() method is used to skip the given number of bytes of content (n_bytes) from this BufferedInputStream.
• 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 may throw an exception at the time skipping bytes.
  IOException: This exception may throw while performing input/output operation or it un-supports seek().

Syntax:

    public long skip(long n_bytes);

Parameter(s):

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

Return value:

The return type of the method is long, it returns n_bytes (i.e. number of bytes) to be skipped.

Example:

// Java program to demonstrate the example 
// of long skip(long n_bytes) method of 
// BufferedInputStream

import java.io.*;

public class demo {
    public static void main(String[] args) throws Exception {
        // To open text file by using 
        // FileInputStream
        FileInputStream fis = new FileInputStream("e:/includehelp.txt");

        // By using BufferedInputStream() isto change
        // the stream fis into buff_str
        BufferedInputStream buff_str = new BufferedInputStream(fis);

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

        // Read character from the stream
        char ch1 = (char) buff_str.read();
        char ch2 = (char) buff_str.read();
        char ch3 = (char) buff_str.read();
        char ch4 = (char) buff_str.read();

        System.out.println("ch1: " + ch1);
        System.out.println("ch2 : " + ch2);
        System.out.println("ch3: " + ch3);
        System.out.println("ch4 : " + ch4);

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

        char ch = (char) buff_str.read();
        System.out.println("ch: " + ch);

        fis.close();
        buff_str.close();
    }
}

Output

Left avail bytes = 33
ch1: H
ch2 : e
ch3: l
ch4 : l
ch: .
