Querying, then generating ArrayLists with variable names

Question

Hi, all:
I have two problems: first, I want to run through an array list called nodeList containing Nodes, each of which possesses a 5-digit value called culture. I want each Node to try to find out whether or not there are any other Nodes that have the same culture value that it does, i.e. if Node i has culture value 74936 and there are 4 other Nodes with the same culture value, I need to find 5 total Nodes with culture value 74936.
  public void statistics(){
       for (int i = 0; i < nodeList.size (); i++) {
            Node node = (Node) nodeList.get (i);
            int cultSame = node.getCulture();
            boolean same = cultSame == next.cultSame;
            if (same == true){
                 arrayListCreator();
                 //generated Arraylist add.node;
  }I'm going astray at next.cultSame. I'm not sure how to structure the query to the ArrayList nodeList to find all the other Nodes with the same culture value.
Second: I want to create a little method to generate ArrayLists with names based on the integers that will be stored in them. Here's the method so far:
  public void arrayListCreator () {
       String name = String.valueOf(cultSame);
       name = new Arraylist();
  }cultSame is a 5-digit integer. The ArrayLists will be used to store all the nodes with the same cultSame value, like 74936, or whatever. If the ArrayList is storing nodes with the cultSame value of 74936, I want the name of the ArrayList to be the string 74936. I want to call on this method (like you can see in the first method) to generate the ArrayList with its given name and then use it to store the nodes in it. Once I've done that, I can figure out the statistics stuff on my own, I think. I'm just not sure how to create the ArrayLists with a name that's a variable, i.e. "name" should be the string variable containing a 5-digit number.

I probably should have separated this out into two threads. First, I'd like to know what I'm doing wrong when I'm building that boolean query to find out in the nodeList if any of the other nodes have the same culture value as the node doing the querying.Then by all means do so, from the looks of it, the scope of the thngs that need to be discussed/addressed is too broad for one thread. First there's the issue of your erroneous understanding of variable, then there's the concept of the Map data structure, then the implementation of it in Java, along with the idea of interface
