如何将字符串转换为 ArrayList? [英] How to convert a String into an ArrayList?

问题描述

在我的字符串中，我可以有任意数量的以逗号分隔的单词.我希望将每个单词添加到 ArrayList 中.例如:

String s = "a,b,c,d,e,........";

解决方案

尝试类似的事情

ListmyList = new ArrayList(Arrays.asList(s.split(",")));

• Arrays.asList 文档
• String.split 文档
• ArrayList(Collection) 构造函数文档

演示:

String s = "lorem,ipsum,dolor,sit,amet";列表<字符串>myList = new ArrayList(Arrays.asList(s.split(",")));System.out.println(myList);//打印 [lorem、ipsum、dolor、sit、amet]

In my String, I can have an arbitrary number of words which are comma separated. I wanted each word added into an ArrayList. E.g.:

String s = "a,b,c,d,e,.........";

解决方案

Try something like

List<String> myList = new ArrayList<String>(Arrays.asList(s.split(",")));

• Arrays.asList documentation
• String.split documentation
• ArrayList(Collection) constructor documentation

Demo:

String s = "lorem,ipsum,dolor,sit,amet";

List<String> myList = new ArrayList<String>(Arrays.asList(s.split(",")));

System.out.println(myList);  // prints [lorem, ipsum, dolor, sit, amet]
