Extract from ArrayList without duplicate

Question

Here is my acctual "headache":
I simply am trying to extract objects from an ArrayList into another. The thing is that the other shouldnt contain any duplicate.
i am trying this:
String[] rowValues;
               //Label label = null;
               int rowCount = 0;
               Individual newIndividual= null;
               List<Individual> individuals = new ArrayList<Individual>();
               List<Individual> temp = new ArrayList<Individual>();
               // TODO Performance test
               // Populating xls file
               while ((rowValues = p.getLine()) != null){                    
                    // find the Individual+ column
                    newIndividual = new Individual(
                               rowValues[PerformanceReportStyleEnum.INDIVIDUAL_PLUS.COLUMN_NUMBER()],
                               rowValues[PerformanceReportStyleEnum.GROUP_PLUS.COLUMN_NUMBER()]);
                    if (rowCount == 1){
                         individuals.add(newIndividual);
                         temp = individuals;
                         rowCount++;
                         continue;
                    for (Individual item : temp) {
                         if (item.getName().equals(rowValues[PerformanceReportStyleEnum.INDIVIDUAL_PLUS.COLUMN_NUMBER()])) {
                              // do nothing
                         else {
                              individuals.add(newIndividual);
                    temp = individuals;
                    rowCount++;     
               for (Individual item : individuals) {
                    System.out.println("Name: " + item.toString());
               }any suggestion? i am quite a newbie to figure it oout myself ;)

Answer 1

but of course... the set could assure uniqueness :-)
so i now tried this:
Set<Individual> individuals = new HashSet<Individual>();
               // TODO Performance test
               // Populating xls file
               while ((rowValues = p.getLine()) != null){
                    // find the Individual+ column
                    newIndividual = new Individual(
                               rowValues[PerformanceReportStyleEnum.INDIVIDUAL_PLUS.COLUMN_NUMBER()],
                               rowValues[PerformanceReportStyleEnum.GROUP_PLUS.COLUMN_NUMBER()]);
                    boolean add = false;
                    if (!individuals.contains(newIndividual)) {
                         add = true;
                    else {
                         add = false;
                    if (add)individuals.add(newIndividual);
                    rowCount++;     
               Iterator<Individual> iter = individuals.iterator();
               int counter = 0;
               while (iter.hasNext()) {
                    System.out.println(((Individual)iter.next()).getName());
                    counter++;
               }this doesnt help though since the if (!individuals.contains(newIndividual)) {
always seems to be true (or rather !true) and therefor duplicates occurs. what i am missing?
thx for your quick answer.
