ObjectInputStream Class skipBytes() method

  • skipBytes() method is available in java.io package.
  • skipBytes() method is used to skip the given number of bytes from the stream.
  • 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 when getting any input/output error while performing.


    public int skipBytes(int number);


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

Return value:

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


// Java program to demonstrate the example 
// of int skipBytes(int number)
// method of ObjectInputStream

import java.io.*;

public class SkipBytesOfOIS {
 public static void main(String[] args) throws Exception {
  // Instantiates ObjectOutputStream , ObjectInputStream 
  // FileInputStream and FileOutputStream
  FileOutputStream file_out_stm = new FileOutputStream("D:\\includehelp.txt");
  ObjectOutputStream obj_out_stm = new ObjectOutputStream(file_out_stm);
  FileInputStream file_in_stm = new FileInputStream("D:\\includehelp.txt");
  ObjectInputStream obj_in_stm = new ObjectInputStream(file_in_stm);

  // By using writeUTF() method is to write
  // the encoded string in UTF-8 to the 
  // obj_out_stm stream
  obj_out_stm.writeUTF("JAVA WORLD");


  // By using skipBytes() method is to skip
  // bytes of data to the stream	
  int skip_byte = obj_in_stm.skipBytes(2);
  System.out.println("obj_in_stm.skipBytes(2): " + skip_byte);

  while (obj_in_stm.available() > 0) {
   // By using readByte() method is to read
   // corresponding byte from the obj_in_stm 
   byte val = (byte) obj_in_stm.readByte();
   System.out.println("obj_in_stm.readByte(): " + val);

  // By using close() method is to 
  // close all the streams 


obj_in_stm.skipBytes(2): 2
obj_in_stm.readByte(): 74
obj_in_stm.readByte(): 65
obj_in_stm.readByte(): 86
obj_in_stm.readByte(): 65
obj_in_stm.readByte(): 32
obj_in_stm.readByte(): 87
obj_in_stm.readByte(): 79
obj_in_stm.readByte(): 82
obj_in_stm.readByte(): 76
obj_in_stm.readByte(): 68
