How to implement this? please help

Question

In my java class, I have a string array called strarray which hold serveral elements, some of the elements have the same value , for example, the first element is "swimming", the forth element is also swimming. I use a for loop to get each element and give it to arrayHolder which is also a array with the same size as strarray. Now, what I want is: I defined a Vector called element I want this vector to filter out the element from arrayHolder, get the name of non-duplicated name from the arrayHolder, the result should be inside the element vector (swimming,walking,running,dancing), no duplicated name. My code is like follows:
import java.util.*;
import java.io.*;
public class arrayTest{
public static void main(String arg[]){
String[] strarray={"swimming","running","walking","swimming","dancing","running"};
String[] arrayHolder=new String[strarray.size];
Vector element=new Vector();
for(int i=0;i<strarray.length();i++){
arrayHolder[  i  ]=strarray[  i  ];
/* What should I do next to get the non-duplicated element from arrayHolder and
* add them into the element vector????
I did not finnish it, since I am a little bit confused, how to implement? Need some help. thanks.

Not sure if I see the use of strArray & arrayHolder (I've not looked at your code - you might use code tags next time (check the "code" button above the message textarea), but may I suggest using a Map of some sort instead of a Vector? It will prevent duplicates for you.
Good Luck
