Given a file with some text and we have to print text after skipping some bytes using FileInputStream in Java.

There is a file named "IncludeHelp.txt" which is stored at my system in "E:" drive under "JAVA" folder (you can choose your path), and file contains the following text,

The quick brown fox jumps over the lazy dog.

Example:

File's content is: "The quick brown fox jumps over the lazy dog."
After skipping starting 10 bytes...
Output: "brown fox jumps over the lazy dog."

Consider the program

import java.io.*;

public class Skip {
  public static void main(String[] args) {
    //file class object     
    File file = new File("E:/JAVA/IncludeHelp.txt");

    try {
      FileInputStream fin = new FileInputStream(file);
      int ch;

      System.out.println("File's content after 10 bytes is: ");

      //skipping 10 bytes to read the file
      fin.skip(10);

      while ((ch = fin.read()) != -1)
        System.out.print((char) ch);
    } catch (FileNotFoundException ex) {
      System.out.println("FileNotFoundException : " + ex.toString());
    } catch (IOException ioe) {
      System.out.println("IOException : " + ioe.toString());
    } catch (Exception e) {
      System.out.println("Exception: " + e.toString());
    }
  }
}

Output

File's content after 10 bytes is: 
brown fox jumps over the lazy dog.
