Hi,
Performance wise, is there really a big difference between using:
- ArrayList.contains(o) vs foreach|iterator
- LinkedList.contains(o) vs foreach|iterator
- HashMap.(containsKey|containsValue) vs foreach|iterator
- TreeMap.(containsKey|containsValue) vs foreach|iterator
Of course, for the foreach|iterator loops, I'll have to explicitly compare the methods and return true or false accordingly.
The object I'm comparing is an object where equals() and hashcode() are both properly overridden.
