Best ResponseYou've already chosen the best response.0If you can use an ArrayList instead, you can use the existing method 'contains'. If not, you could copy the implementation in java: public boolean contains(Object o) { return indexOf(o) >= 0; } where indexOf is: public int indexOf(Object o) { if (o == null) { for (int i = 0; i < size; i++) if (elementData[i]==null) return i; } else { for (int i = 0; i < size; i++) if (o.equals(elementData[i])) return i; } return 1; } If you know the list is sorted, you can use a binary search.
