Replacing characters in Java

Question

I tried to replace characters in String which works sometimes and does not work most of the time.

I tried the following:

String t = \"[javatag]\";
String

String objects in java are immutable. You can't change them.

You need:

t2 = t2.replace("\\]", "");

replace() returns a new String object.

Edit: Because ... I'm breaking away from the pack

And since this is the case, the argument is actually a regex, and you want to get rid of both brackets, you can use replaceAll() instead of two operations:

t2 = t2.replaceAll("[\\[\\]]", "");

This would get rid of both opening and closing brackets in one fell swoop.
