Escape character for []

[Gregers Svensson]

Hey !

I've a method that should split some parts of an String. If the string contains [ or ] it should split them. Like this:

String[] parts = tf.split("[");
String part1 = parts[0];
String part2= parts[1];

Why dosen't this code work?

It says" Invalid regular expression; Unclosed character Class." If i hover over the ("[") part....

Thanks in advance!

because in a regex, the bracket has special meaning - it is for a group of characters. So you can say [12378] and it treats them as "match any single one of these".

try using the backslash. I don't KNOW it will work, but I THINK it wil..

Ye, I tried with backslash, didn't work , ''


("\\[*") did it! , or atleast I think it did !

Backslash itself is also special character in Java and so has to be escaped by another backslash.
