I have an
ArrayList, a Collection class of Java, as follows:
ArrayList<String> animals = new ArrayList<String>(); animals.add("bat"); animals.add("owl"); animals.add("bat"); animals.add("bat");
As you can see, the
ArrayList consists of 3
bat elements and one
owl element. I was wondering if there is any API in the Collection framework that returns the number of
bat occurrences or if there is another way to determine the number of occurrences.
I found that Google's Collection
Multiset does have an API that returns the total number of occurrences of an element. But that is compatible only with JDK 1.5. Our product is currently in JDK 1.6, so I cannot use it.
