Copying ArrayList to same and subtype ArrayLists?

In your second for loop you have:

for (int i = 1; i <
orderProcessor.size(); i++){

If orderProcessor only had 1 order in it, then it would never get added to your coumputerPart arrayList because i would not be less than orderProcessor.size(). You can also check the types of your sub classes to add them into the correct ArrayList. Like this (with the int i = 0 fix):

for (int i = 0; i <
orderProcessor.size(); i++){
    if (orderProcessor.elementAt(i) instanceof

*(I would've commented on this, but I don't have enough rep points...)

Most efficient way to split one arraylist data into 4 seperate arraylists?

hash map with arraylist and create new arraylist out of it
Get your ArrayList 2a. If it doesn't exist - put your new ArrayList 2b. Else USE this ArrayList. It's mutable. So you can call .add on this object and it will be updated in HashMap Try this: for (String type: allTypes) { if (fData.get(type).size() > 0) { arraySort(fData.get(type)); if (cData.get(type) == null) { temp = new ArrayList<Integ
