LineNumberInputStream Class skip() method

  • skip() method is available in java.io package.
  • skip() method is used to skip the given number of the byte of data from this LineNumberInputStream 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 may throw an exception at the time of skipping bytes of 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 to be skipped.

Example:

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

import java.io.*;

public class SkipOfLNIS {
 public static void main(String[] args) throws Exception {
  FileInputStream fis_stm = null;
  LineNumberInputStream line_stm = null;
  int val = 0;

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

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

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

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

    // By using skip(2) method is to skip
    // 2 bytes of char from the line_stm 

    long skip = line_stm.skip(2);
    System.out.println("line_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 (line_stm != null) {
     line_stm.close();
    }
   }
  }
 }
}

Output

ch: J :line_stm.skip(2): 2
ch: A :line_stm.skip(2): 2
ch: R :line_stm.skip(2): 2
