Java regex with reserved chars

Question

I'm using a pattern string like this

url = "http://myWebsite.com:1700/[LANG]/service/?customerid=[CUSTOMERID]";

I'm using this code to replace parameters.

url.replace("[LANG]", languageName);

also tryied :

url.replace("\\[LANG\\]", languageName);

but not worked.

You mean you tried `url = url.replace("[LANG]", languageName);`? — Wiktor Stribiżew, Aug 05 '15 at 11:12

Java Strings are immutable. replace() returns a new string and you need to capture it:

url = url.replace("[LANG]", languageName);

If it is an answer, the question is a duplicate. – Wiktor Stribiżew Aug 05 '15 at 11:14
@stribizhev Sure. For simple answers like this it takes less time to write an answer than to search for a canonical duplicate. – laalto Aug 05 '15 at 11:16
@stribizhev ...and I bet that duplicate is also duplicate. – Pshemo Aug 05 '15 at 11:16
I found one very quickly. But I wanted to hear from OP first whether the assignment to the variable actually took place. – Wiktor Stribiżew Aug 05 '15 at 11:17
@stribizhev In that case feel free to use your hammer early. If OP will update his question with more details you can propose new duplicate another mjolnir owner can reopen this question and use new duplicate. – Pshemo Aug 05 '15 at 11:20
@Pshemo: I just have a strong trust in people :) that is my Kryptonite. – Wiktor Stribiżew Aug 05 '15 at 11:22
