Question

I am having trouble printing out individual Strings from Interable object.
I have this given function prefixMatch(String someword) that returns Iterable (that keeps a LinkedList of Strings, I think). I have tried turning it into a list but it wont work. Dose anyone know how to get the Strings out of it one by one?

tst is a Ternary search tree

Iterable<String> words = tst.prefixMatch(word);

Answer 1

If it’s Iterable you can do an extended for on it.

Iterable<String> iterable;
for(String s : iterable){
    //Do whatever you want
}
