Question

Whats the quickest way to put a set into a map?

public class mySet<T> 
{
    private Map<T, Integer> map;

    public mySet(Set<T> set) 
    {
        Object[] array = set.toArray();

        for(int i =0; i< array.length; i++)
        {
            T v = (T)array[i];
            map.put(v, 1);
        }
    }
}

Right now, I just converted set into an array and loop through the array and putting them in one by one. Is there any better way to do this?

One options would be this:

for (T value : set) {
  map.put(value, 1);
}
