Parsing e-mails

Question

Hi Guys,
I'm trying to figure out a simple way to use regex (or any other alternative) to parse e-mails from a text file...
let's say I have a text file, "something test [email protected] more test and now another [email protected] and that's it"
Anyone have ideas as far as parsing a string to extract e-mails only? I think regex is the way to go, but I don't even know where to start.
Thanks
Lucy,

I wouldn't know how to extract multiple e-mail addresses from a String using the dark force called regex.
But here's another way to achieve it:
     public String[] getEMailAddresses(String str) {
          List<String> list = new ArrayList<String>();
          while(str.indexOf('@') != -1) {     
               int index = str.indexOf('@');
               int begin = 0;
               int end = 0;
               for(int i = index-1; i >= 0; i--)
                    if(str.charAt(i) == ' ') { begin = i+1; break; }
               for(int i = index+1; i < str.length(); i++)
                    if(str.charAt(i) == ' ') { end = i;      break; }
               list.add(str.substring(begin, end));
               str = str.substring(0, begin)+str.substring(end, str.length());
               System.out.println(str);
          return list.toArray(new String[list.size()]);
     }Note: this code does not look for valid e-mail addresses and there are numerous things that can go wrong! Debug it and adjust it to your needs if you wish.
Good luck.
