variable may not have been initialized??...

I am trying to use a Collection, but when I try to compile, I get an error saying that the collection may not have been initialized at this line:

colData.add("Hello");
^

so how do I initialize a Collection?

Thanks

How did you do it in your code?

Collection myCol = new Collection();

I don't think that you can do this. I may be wrong but I believe that there's only three types of collections:

Sets:

• HashSet
• TreeSet

Lists:

• Vector
• Stack
• LinkedList
• ArrayList

Maps:

• HashTable
• HashMap
• WeakHashMap
• TreeMap
