问题描述

在Java中有什么内置方法，允许我们将逗号分隔的字符串转换为某个容器（例如array，List或Vector）？或者我需要为此编写自定义代码？

Is there any built-in method in Java which allows us to convert comma separated String to some container (e.g array, List or Vector)? Or do I need to write custom code for that?

String commaSeparated = "item1 , item2 , item3";
ArrayList<String> items = //method that converts above string into list??

推荐答案

Convert comma separated String to ArrayList

List<String> items = Arrays.asList(str.split("\\s*,\\s*"));
