Question

I am using a for loop to iterate through a list of arrays that all have the same name expect a different number at the end. For example child1, child2, etc. I though if I tried childi where i is the variable that I would be able to loop through all the arrays. However, that did not work. I have change i from an int to a string and concatenating it on the end, but then I get a new variable that is not the same at the array. Any ideas.

        int i=0;
        String []child=childi;//so child would refer to child0 then child1
        for (int j = 0; j < child.length(); j++) {
            Map<String, String> curChildMap = new HashMap<String, String>();
            children.add(curChildMap);
            curChildMap.put(NAME, child[j]);
            curChildMap.put(IS_EVEN, (j % 2 == 0) ? "This child is even" : "This child is odd");
        }   
         i++

You cannot reference a variable by a dynamically computed name. In this case your best bet is probably to create an array or other container to hold your child arrays. For example,

String[][] children = new String[][] { child0, child1, child2, child3, /* ... */ };
for (int i = 0; i < children.length; i++) {
  String[] child = children[i];
  for (int j = 0; j < child.length(); j++) {
    Map<String, String> curChildMap = new HashMap<String, String>();
    children.add(curChildMap);
    curChildMap.put(NAME, child[j]);
    curChildMap.put(IS_EVEN, (j % 2 == 0) ? "This child is even" : "This child is odd");
  }   
}
