JAVA 链表如何使用 for 循环进行循环? [英] JAVA Linked List How to loop through with a for loop?

问题描述

您好，我正在尝试创建一个循环遍历链表的 for 循环.对于每条数据，它将单独列出.我正在尝试在这里学习链表，所以请不要提供数组建议.有人知道怎么做吗?

Hello I am trying to create a for loop that loops through the linked list. For each piece of data it will list it out individually. I am trying to learn linked list here, so no Array suggestions please. Anyone know how to do this?

示例输出:

1. 187 号航班
2. 501 航班

<小时>

我在下面的代码:

---

CODE I HAVE SO FAR BELOW:

public static LinkedList<String> Flights = new LinkedList<String>();

public flightinfo(){
String[] flightNum = {"187", "501"};
        for (String x : flightNum)
        Flights.add(x);

                for (???)


}

推荐答案

只需使用增强的 for 循环，就像使用数组一样:

Just use the enhanced for-loop, the same way you'd do it with an array:

for(String flight : flights) {
   // do what you like with it
}
