How can I get inside parentheses value in a string?

android, java

Solution

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
