java 如何从 Iterable<String> 打印出单个字符串

How to print out individual Strings from Iterable<String>

提问by user1303750

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?

我无法从 Interable 对象打印出单个字符串。我有这个给定的函数 prefixMatch(String someword) 返回 Iterable （我认为它保留了一个字符串的 LinkedList ）。我试过把它变成一个列表，但它不起作用。有谁知道如何将字符串一一取出？

tst is a Ternary search tree

tst 是一个三元搜索树

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

If it's Iterableyou can do an extended for on it.

如果是，Iterable您可以对其进行扩展。

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

The java 8 way, using forEach:

java 8 方式，使用forEach：

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

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

我认为这会对你有所帮助，我在这里使用 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());

        }
