Is there a good way to have a Map<String, ?> get and put ignoring case? [duplicate]

Answer 1

You need a wrapper class for your String key with a case-insensitive equals() and hashCode() implementation. Use that instead of the String for the Map's key.

See an example implementation at http://www.java.happycodings.com/Java_Util_Package/code3.html I found it in 2 minutes of googling. Looks sensible to me, though I've never used it.
