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 [ ,

First, you don't want to split on the brackets. You just want to exclude them from your end result. So first thing you'll probably want to do is strip those out:

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

Then you can do a basic split on the comma:

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

I would do it in one line, first removing the square brackets, then splitting:

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