How to split a String to an ArrayList?
提问by
I know there is a String split method that returns an array but I need an ArrayList.
我知道有一个 String split 方法可以返回一个数组，但我需要一个 ArrayList。
I am getting input from a textfield (a list of numbers; e.g. 2,6,9,5) and then splitting it at each comma:
我从文本字段（数字列表；例如2,6,9,5）获取输入，然后在每个逗号处将其拆分：
String str = numbersTextField.getText();
String[] strParts = str.split(",");
Is there a way to do this with an ArrayList instead of an array?
有没有办法用 ArrayList 而不是数组来做到这一点？

You can create an ArrayList from the array via Arrays.asList:
您可以通过Arrays.asList从数组创建一个 ArrayList ：
ArrayList<String> parts = new ArrayList<>(
Arrays.asList(textField.getText().split(",")));
If you don't need it to specifically be an ArrayList, and can use any type of List, you can use the result of Arrays.asList directly (which will be a fixed-size list):
如果你不需要它专门是一个 ArrayList，并且可以使用任何类型的 List，你可以直接使用 Arrays.asList 的结果（这将是一个固定大小的列表）：
List<String> parts = Arrays.asList(textField.getText().split(","));

There is no such thing as a Split functionfor list, but you can do the split and then convert to a List
没有列表的拆分函数之类的东西，但是您可以进行拆分然后转换为列表
List myList = Arrays.asList(myString.split(","));
