Java String ReplaceAll (Regex Help) [closed]

Question

I have the following String:

String str1= "ABCD";

I want the following String

String str2 = "AD"

Therefore, I would like something along the lines of this:

String str2 = str1.replaceAll("/* SOME REGEX HERE */", "");

How can I write the regex so that both "B" and "C" are replaced?

Do you mean to replace all characters between A and D? Between the first and the last? Your problem is ambiguous. — Patashu, Apr 10 '13 at 2:43
@androideka sorry to ask, but can you undelete your last question (time difference in Java/Android)? I already have prepared an answer. — Luiggi Mendoza, Apr 10 '13 at 21:18

You could write it as...

String str2 = str1.replaceAll("[BC]", "");
