RandomAccessFile Class skipBytes() method

  • skipBytes() method is available in java.io package.
  • skipBytes() method is used to skip the given number of bytes in this file and possibly set the given parameter to the least value 0.
  • skipBytes() 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.
  • skipBytes() method may throw an exception at the time of skipping bytes.
    IOException: This exception may throw an exception while performing input/output operation.

Syntax:

    public void skipBytes(int no_of_byte);

Parameter(s):

  • int no_of_byte – represents the number of bytes to skip.

Return value:

The return type of this method is int, it returns the skipped bytes.

Example:

// Java program to demonstrate the example 
// of void skipBytes(int no_of_byte) method of
// RandomAccessFile

import java.io.*;

class RAFSkipBytes {
 public static void main(String[] args) throws Exception {
  // Instantiate a random access file
  // object with file name and permissions
  RandomAccessFile ra_f = new RandomAccessFile("e:/includehelp.txt", "rw");

  // By using writeUTF() method is to 
  // write data to the file
  ra_f.writeUTF("Welcome in Java World!!!");

  // by using seek() method is to 
  // set the current file indicator
  // from where read/write could 
  // start i.e. we set here 0 so reading
  // will be done from 0 till EOF
  ra_f.seek(0);

  // By using readUTF() method is to 
  // read a data in a string from
  // this file
  System.out.println("ra_f.readUTF(): " + ra_f.readUTF());

  // By using skipBytes() method isto
  // return the given number of bytes to
  // be skipped 

  int bytes = ra_f.skipBytes(2);
  System.out.println("ra_f.skipBytes(2): " + bytes);

  // By using close() method isto
  // close this stream ran_f
  ra_f.close();
 }
}

Output

ra_f.readUTF(): Welcome in Java World!!!
ra_f.skipBytes(2): 2
