Parallel vectors synchronize

Hello,
in my code i have at some point 3 parallel vectors [float(i)<=>string1(i)<=>string2(i)]

i wanted to eliminate equal float numbers of the 1st vector ,therefore i create a SET which works fine:

Code :

---

Set unique = new LinkedHashSet();
          Iterator iter;
          for ( iter = unique.iterator(); iter.hasNext();) {
                 Object obj = iter.next();
                 System.out.println("/unique vector/ " + obj);}

---

Im having difficulty at deleting the correspoding strings of the other 2 vectors,although it sounds pretty easy to do.
i would appreciate any ideas!
thnx very much a priori:o

How are you loading the Set from the Vector? If you did that in a loop you would have the index needed to access the other two Vectors.

its loaded outside the loop ,and moving that control inside the loop would cause more problems

How is that?

inside the loop i find dynamically the values of float numbers and the correspodining values of string1 and string 2
if i try to create the set inside the loop then the values are not correct(unless im missing something)

PS:now that i think of it , its more convenient to find a way to eliminate duplicates
a SET contains the unique values and not only the duplicates if im correct

Inside the loop that is creating the Vectors, you could use the Set to tell you if the current float is already in the Set.

i am trying that but i cant make it work. I have a loop inside a loop and that makes things worse

Don't be scare of loops inside loops. It is a VERY common practice. I think I've gone further than 7 loops deep before.

Can you explain what problems you are having?
