如何从Iterable< String>打印单个字符串

问题描述

限时删除！！

我无法从Interable对象中打印出各个字符串.我有这个给定的函数prefixMatch(String someword)返回Iterable(我认为它保留了Strings的LinkedList).我曾尝试将其转换为列表，但无法正常工作.有谁知道如何一一拿出琴弦?

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是三元搜索树

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

推荐答案

如果它是 Iterable ，您可以对其进行扩展.

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

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