Bellow it is your code. I have used lines to split text and Tim's regular expression.

import java.util.Scanner;
import java.io.*;
import java.util.regex.*;
import java.util.ArrayList;
/**

public class RegexSimple41 {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
       ArrayList  manyLines = new ArrayList();
       ArrayList  noRepeat = new ArrayList(); 
        try
        {
            Scanner myfis = new Scanner(new File("D:\\myfis41.txt"));

            while(myfis.hasNext())
            {
                String line = myfis.nextLine();
                String delim = System.getProperty("line.separator");
                String [] lines = line.split(delim);

                for(String s: lines)
                {
                    if(!s.isEmpty()&&s!=null)
                    {
                        manyLines.add(s);
                    }
                }
            }
            if(!manyLines.isEmpty())
                    { System.out.print("Original text\n");
                        for(String s: manyLines)
                        {
                            System.out.println(s);
                }
                        }
            if(!manyLines.isEmpty())
                    { 
                        for(String s: manyLines)
                        {
                            String result = s.replaceAll("(?i)\\b([a-z]+)\\b(?:\\s+\\1\\b)+", "$1");
                            noRepeat.add(result);
                }
                        }
             if(!noRepeat.isEmpty())
                    { System.out.print("Remove duplicates\n");
                        for(String s: noRepeat)
                        {
                            System.out.println(s);
                }
                        }

        }

        catch(Exception ex)
        {
            System.out.println(ex);
        }
    }

}

Good luck,
