hi i have written  a function to get the arraylist`s index values  that contain the number occurrences of  each state.The csv file is 24499 rows and 3 columns

1.  String [] states=new String [24499];
    String [] stateNames(){
      for (int i=0; i<data.length; i++){
        states[i]=csv[i][0];
          }
      return states;
    }
   
2. 
   
3.  //in this function s is a string that holds one state name  with a leftClick mouseFunction
   
4. void  indices(){
5.    int occurences=0;
6.  
7.  
8.   List myList=Arrays.asList(stateNames()); //
9.  Iterator iterator=myList.iterator();
10.  while(iterator.hasNext()){
11.    println((String) iterator.next());  //it breaks without this line(?)
    
12.  }
13.  if (myList.contains(s)){
14.    occurences=Collections.frequency(myList,s);
15.    }
16.  
17.    List<Integer> indices=new ArrayList<Integer>(occurences);
18.      for (int i=0; i<occurences; i++){
19.       if(s.equals(myList.get(i))){
20.        indices.add(i);
21.       }
22. }
23. print(s+" "+occurences+" " );
24. println(indices);
25.  }

the strange thing is that i get the number of occurrences correct for all states but the index values are correct *only* for two states (i get no values (a blank [] ) for the rest of the states)...anyone has an idea why this might be happening?

its the first time i use collections etc, is this the correct way to do something like this?...what i want to do (if it helps) is get the index values,store them in an array and then for these values draw some points with csv[indexValues][1] and csv[indexValues][2]

last thing: is it possible to write functions like
Arraylist something(){
//blabla
} return somethingElse;

without using generics?
