How to print out individual Strings from Iterable<String>

问题

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);

回答1:

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

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

回答2:

for (String s: words) {
    System.out.println(s);
}

回答3:

The java 8 way, using forEach :

words.forEach(word-> System.out.println(word));

I think this will help you, here i am using Iterable.

TreeSet treeSet = new TreeSet<String>();
        treeSet.add("A");
        treeSet.add("B");

        Iterable<String> it = treeSet;

        Iterator iterator = it.iterator();
        while (iterator.hasNext()) {
            System.out.println(iterator.next());

        }
