Ok, there are a few different ways this can be done, heres what I did:

Code:

---

import java.util.*;
public class DublicateRemoval
{
  public static void main (String[] args)
  {
    Scanner myInput = new Scanner(System.in);
    String words = myInput.nextLine();
   
    //removing spaces
    words = words.replaceAll(" ", "");
   
    //replace duplicates
    String temp = "";
    int position = 0;
    while(position < words.length())
    {
      temp = words.substring(position + 1);
      temp = temp.replaceAll(words.charAt(position) + "", "");
      //System.out.println(temp);
      //System.out.println(words.substring(0, position+1));
      words = words.substring(0, position + 1) + temp;
      position ++;
  }
   
    System.out.println(words);
  }
}
