split into a 2d array

Hi, I'm bringing in a string and I'm trying to split it so new vectors can be properly arranged in a arrayList<arrayList<myclass>>myarray, but I am having trouble with the spliting part. What a I have is S number of sets with N number of nodes with 3 coords each. The error so far (god know how many others are there) is "unexpected token:]" on line

sets2d[i][] = split (sets[i], 'n');

any ideas on what am I doing wrong or where to look for the right answer? thanks!

ArrayList<ArrayList<Mover>>movers2d = new ArrayList<ArrayList<Mover>>();

message = new String( data );

String[] sets = split (message, 's');

string[][]sets2d = new string[sets.length][];

for (int i = 0; i<sets.length; i++) {

      sets2d[i][] = split (sets[i], 'n'); // here is the error

}



for(int i=0; i<lines.length; i++){

movers2d.add(new ArrayList<Mover>());

for(int j=0; j<lines[i].length; j++){

if (lines[i].startsWith("]")){

float values[] = float(sets2d[i][j].split("]")[1].split( ","));

movers2d.get(i).add( new Mover(new PVector( values[0], values[1], values[2]) ));

}

}

}

hi, I'm trying to import 3d coordinates from grasshopper but I just cant figure it out. I have tried to search in the forum, and both the gHowl and UPD Lib examples, and so far this is what i have. But I'm stuck with NullPointerExceptionAny thoughts? If someone has an example of multiple points transfer from GH to processing that would be rather helpful. Thanks in advance for any help
1. import hypermedia.net.*;
2. UDP udpr;
3. String message;
4. ArrayList nodesGH = new ArrayList();
7. void setup() {
8. udpr = new UDP( this, 600);
9. udpr.listen( true );
11. String lines[] = split(message, ']');
12. // println(lines.length);
13. for(int i = 0; i<lines.length; i++){
14. if (lines[i].startsWith("#")){
15. float values[] = float(lines[i].split("#")[1].split( ","));
16. // nodesGH.add( new Node(values[0], values[1], values[2]) );
17. }
18. }
19. }
21. void draw(){
22. }
24. void receive( byte[] data, String ip, int port ) {
25. data = subset(data, 0, data.length);
26. message = new String( data );
28. // print the result
29. println( "receive: \""+message+"\" from "+ip+" on port "+port );
32. }
35. class Node{
36. Ball(float x, float y, float z){
37. println( " generated new Ball: "+ x +", "+y+", "+z);
38. }
39. }
