如何在 Java 中对字符串的 ArrayList 进行排序? [英] How can I sort an ArrayList of Strings in Java?

问题描述

我将 String 随机放入 ArrayList 中.

I have Strings that are put into an ArrayList randomly.

private ArrayList<String> teamsName = new ArrayList<String>();
String[] helper; 

例如:

teamsName.add(helper[0]) where helper[0] = "dragon";   
teamsName.add(helper[1]) where helper[1] = "zebra";   
teamsName.add(helper[2]) where helper[2] = "tigers" // and so forth up to about 150 strings.

鉴于您无法控制输入(即进入 ArrayList 的字符串是随机的；斑马或龙以任何顺序排列)，一旦 ArrayList 填充了输入，我如何按字母顺序对它们进行排序(第一个除外)?

Given the fact that you cannot control the inputs (i.e. string that is coming into the ArrayList is random; zebra or dragon in any order), once the ArrayListis filled with inputs, how do I sort them alphabetically excluding the first one?

teamsName[0] 没问题；按字母顺序对 teamsName[1 to teamName.size] 进行排序.

teamsName[0] is fine; sort teamsName[1 to teamsName.size] alphabetically.

推荐答案

Collections.sort(teamsName.subList(1, teamsName.size()));

上面的代码将反映排序后的原始列表的实际子列表.

The code above will reflect the actual sublist of your original list sorted.
