Easily find the end of file that you are processing. Scanner again has a easier way of doing it.

import java.util.*;
import java.io.*;

public class EndOfFile {

   public static void main(String args[])
   {
      EndOfFile endOfFile = new EndOfFile();
      endOfFile.proceed();
   }

   final String fileName = "/mypc/EndOfFile.java";
   
   private void proceed()
   {
      Scanner input = null;
      try
      {
         //initializing the Scanner input with the file name
         input = new Scanner(new File(fileName));
         //Checking if a nextLine exists
         while(input.hasNextLine())
         {
            //Reading the nextLine
            System.out.println(input.nextLine());
         }
      }catch(FileNotFoundException fnf)
      {
         System.out.println("Exception: "+fnf);
         //do Nothing
      }
   }
}

/*
Expected output:

[root@mypc]# java EndOfFile
Will print the complete source code of EndOfFile.java
