java - Java Split on Regex

Question

I cant seem to be able to split on a simple regex,

If i have a string [data, data2] and i attempt to split like so: I tried to escape the brackets.

    String regex = "\\[,\\]";
    String[] notifySplit = notifyWho.split(regex);

The output of looping through notifySplit shows this regex not working

notify: [Everyone, Teachers only]

Any help on what the proper regex is, i am expecting an array like so: data, data2

where i could possibly ignore these two characters [ ,

Answer 1

首先，您不想在括号上拆分。您只想将它​​们从最终结果中排除。所以你可能想做的第一件事就是把它们去掉：

notifyWho = notifyWho.replace("[", "").replace("]", "");

然后您可以对逗号进行基本拆分：

String[] notifySplit = notifyWho.split(",");

Answer 2

我会在一行中完成，首先删除方括号，然后拆分：

String[] notifySplit = notifyWho.replaceAll("[[\\]]", "").split(",");
