How to split in java by "][" ?

[torn lintel]

I'm trying to split a string , but I get 'java.util.regex.PatternSyntaxException' exception because its seeing "][" as Unclosed character class. Anybody knows the escape character for this?

String pattern = "]".concat"["
String toSplit = "|][%";
List<String> splitted = Arrays.asList(toSplit.split(pattern))

I also tried pattern with value "\]\[" but still doens't work. Any suggestions?

"\\]\\["

It doesn't work, this will be seen as "][" and will not be contained in toSplit

i don't see what the issue is

you're not even using toSplit

/run

System.out.println(java.util.Arrays.toString("|][%".split("\\]\\[")));

Here is your java(15.0.2) output @reef urchin

[|, %]

My bad. It actually works in the split, but for some reason it doesn't work in contains():
System.out.println("|][%".contains("\\]\\["));
returns false

[reef urchin]

yes because split uses regex while contains uses normal strings

contains -> ][
split -> \\]\\[

\\]\\[ in regex means the same thing as ][ in a normal string

It works now. Thanks
