Working Code:

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class HelloWorld {

    public static void main(String[] args) {
        Pattern p = Pattern.compile("\\$(\\w.*?)\\$");
        String s = "Hello $everybody$. How $are$ you $all$";

        Matcher m = p.matcher(s);
        while (m.find()) {
                System.out.println(m.group(1));
        }
    }

}
