import java.util.*;
import java.io.*;
public class SplitFile {
   public static void main(String[] args)
   {
       if(args.length!=3)
       {
           System.err.println("Please provide three filenames for the program");
           return;
       }
   PrintWriter file1=null;
   PrintWriter file2=null;
   try
   {
       Scanner scan = new Scanner(new File(args[0]));
       file1 = new PrintWriter(new File(args[1]));
       file2 = new PrintWriter(new File(args[2]));
       while(scan.hasNextLine())
       {
           String s = scan.nextLine();
           file1.print(s);
           if(scan.hasNextLine())
           {
               String s1 = scan.nextLine();
               file2.print(s1);
           }
