FilterInputStream 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 FilterInputStream.
• 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 of data.
  IOException: This exception may throw when the given parameter is invalid.

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 FilterInputStream

import java.io.*;

public class SkipOfFIS {
 public static void main(String[] args) throws Exception {
  FileInputStream fis_stm = null;
  FilterInputStream fil_stm = null;
  int count = 0;

  try {
   // Instantiates FileInputStream and 
   // FilterInputStream
   fis_stm = new FileInputStream("D:\\includehelp.txt");
   fil_stm = new BufferedInputStream(fis_stm);

   // Loop to read until available
   // bytes left
   while ((count = fil_stm.read()) != -1) {

    // Display corresponding char value
    char ch = (char) count;

    // Display value of ch
    System.out.println("ch: " + ch);

    // By using skip() method is
    // to skip 2 bytes of char value
    // from fil_stm	    

    long skip = fil_stm.skip(2);
    System.out.println("fil_stm.skip(2): " + skip);
   }
  } 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 (fis_stm != null) {
    fis_stm.close();

    if (fil_stm != null) {
     fil_stm.close();
    }
   }
  }
 }
}

Output

ch: J
fil_stm.skip(2): 2
ch: a
fil_stm.skip(2): 2
ch: r
fil_stm.skip(2): 2
ch: .
fil_stm.skip(2): 2
ch: .
fil_stm.skip(2): 2
