Example

The following example shows the usage of java.io.ObjectInputStream.skipBytes() method.

package com.tutorialspoint;

import java.io.*;

public class ObjectInputStreamDemo {
   public static void main(String[] args) {
      String s = "Hello World!";
      
      try {
         // create a new file with an ObjectOutputStream
         FileOutputStream out = new FileOutputStream("test.txt");
         ObjectOutputStream oout = new ObjectOutputStream(out);

         // write something in the file
         oout.writeUTF(s);
         oout.writeUTF("This is an example");
         oout.flush();

         // create an ObjectInputStream for the file we created before
         ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

         // skip 4 bytes and read the rest
         ois.skipBytes(4);
         for (int i = 0; i < ois.available() - 4; i++) {
            System.out.print("" + (char) ois.readByte());
         }
      } catch (Exception ex) {
         ex.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result −
