Move specific items to the end of a list

Use custom Comparator:

List<String> strings = Arrays.asList(
        "deleteItem", "createitem", "exportitem", "deleteItems", "createItems"
        );
Comparator<String> comparator = new Comparator<String>() {
    @Override
    public int compare(final String o1, final String o2) {
        if (o1.contains("delete") && !o2.contains("delete")) {
            return 1;
        }else if (!o1.contains("delete") && o2.contains("delete")) {
            return -1;
        }
        return 0;
    }
};
Collections.sort(strings, comparator);
System.out.println(strings);

If you want something efficient and need to remove elements in the beginning and middle of a List I would suggest using a LinkedList instead of a array list. That would avoid rewriting the underlying array for each remove operation.

Then, you simply iterate on the list, calling remove and addLast for any string that contains delete.

Of course, this is only OK if there is nothing preventing you from replacing your ArrayList with a LinkedList.
