How can I get inside parentheses value in a string?

Compiles and prints “AED”. Even works for multiple parenthesis:

import java.util.regex.*;

public class Main
{
  public static void main (String[] args)
  {
     String example = "United Arab Emirates Dirham (AED)";
     Matcher m = Pattern.compile("\\(([^)]+)\\)").matcher(example);
     while(m.find()) {
       System.out.println(m.group(1));    
     }
  }
}

The regex means:

• \\(: character (
• (: start match group
• [: one of these characters
• ^: not the following character
• ): with the previous ^, this means “every character except )“
• +: one of more of the stuff from the [] set
• ): stop match group
• \\): literal closing paranthesis
