Question

How can I get inside parentheses value in a string?

String str= "United Arab Emirates Dirham (AED)";

I need only AED text.

I know this was asked over 4 years ago, but for anyone with the same/similar question that lands here (as I did), there is something even simpler than using regex:

String result = StringUtils.substringBetween(str, "(", ")");

In your example, result would be returned as "AED". I would recommend the StringUtils library for various kinds of (relatively simple) string manipulation; it handles things like null inputs automatically, which can be convenient.

Documentation for substringBetween(): https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#substringBetween-java.lang.String-java.lang.String-java.lang.String-

There are two other versions of this function, depending on whether the opening and closing delimiters are the same, and whether the delimiter(s) occur(s) in the target string multiple times.
