InputStream Class skip() method

• skip() method is available in java.io package.
• skip() method is used to skip the given number of bytes of data from this InputStream.
• 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 of skipping bytes data.
  IOException: This exception may throw when getting any input/output error while performing.

Syntax:

    public long skip(long number);

Parameter(s):

• long number – represents the number of bytes to be skipped.

Return value:

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

Example:

// Java program to demonstrate the example 
// of long skip(long number) method 
// of InputStream

import java.io.*;

public class SkipOfIS {
 public static void main(String[] args) throws Exception {
  InputStream is_stm = null;

  try {
   // Instantiates FileInputStream
   is_stm = new FileInputStream("D:\\includehelp.txt");

   for (int val = 0; val < 8; ++val) {

    // By using read() method is to read
    // a byte from is_stm
    is_stm.read();

    // Display corresponding bytes value
    byte b = (byte) val;

    // Display value of b
    System.out.println("is_stm.read(): " + b);

    // By using skip() method is to skip         
    // 1 bytes data from the is_stm
    long skip_byte = is_stm.skip(1);
    System.out.println("is_stm.skip(1): " + skip_byte);

    System.out.println();
   }

  } catch (Exception ex) {
   System.out.println(ex.toString());

  } finally {
   // with the help of this block is to
   // free all necessary resources linked
   // with the stream
   if (is_stm != null) {
    is_stm.close();
   }
  }
 }
}

Output

is_stm.read(): 0
is_stm.skip(1): 1

is_stm.read(): 1
is_stm.skip(1): 1

is_stm.read(): 2
is_stm.skip(1): 1

is_stm.read(): 3
is_stm.skip(1): 1

is_stm.read(): 4
is_stm.skip(1): 1

is_stm.read(): 5
is_stm.skip(1): 1

is_stm.read(): 6
is_stm.skip(1): 1

is_stm.read(): 7
is_stm.skip(1): 1
