Question

I’ve been here in a battle because of regular expressions ..

I’m getting something like that [5.00,10.00,20.00] and I want to get just the numbers that is, 5.00, 10.00 and 20.00. And do not get tou get a regex that I do this separation

In this case I’m only getting 3 numbers, but can I get more than three.

Someone can help me in the regular expression to do this?

Thanks

Answer 1

Here’s one suggestion:

String input = "[5.00,10.00,20.00]";

String[] parts = input.replaceAll("\\[|\\]", "").split(",");

You could also strip out [ and ] using String.substring without regular expressions.

String[] parts = input.substring(1, input.length() - 1).split(",");

Note that split doesn’t handle the empty string very well in this situation. If you may get "[]" as input, I suggest you do something like

input = input.replaceAll("\\[|\\]", "");
String[] parts = input.isEmpty() ? new String[] {} : input.split(",");
