Open link in browser using java code

A very useful Java code, to open a web browser from Java application in windows or Linux.

public class StartBrowser {

  public static void main(String args[])
  {
String url = "http://www.google.com";
String os = System.getProperty("os.name").toLowerCase();
        Runtime rt = Runtime.getRuntime();

try{

   if (os.indexOf( "win" ) >= 0) {

       // this doesn't support showing urls in the form of "page.html#nameLink"
       rt.exec( "rundll32 url.dll,FileProtocolHandler " + url);

   } else if (os.indexOf( "mac" ) >= 0) {

       rt.exec( "open " + url);

            } else if (os.indexOf( "nix") >=0 || os.indexOf( "nux") >=0) {

       // Do a best guess on unix until we get a platform independent way
       // Build a list of browsers to try, in this order.
       String[] browsers = {"epiphany", "firefox", "mozilla", "konqueror",
                  "netscape","opera","links","lynx"};

       // Build a command string which looks like "browser1 "url" || browser2 "url" ||..."
       StringBuffer cmd = new StringBuffer();
       for (int i=0; i<browsers.length; i++)
           cmd.append( (i==0  ? "" : " || " ) + browsers[i] +" \"" + url + "\" ");

       rt.exec(new String[] { "sh", "-c", cmd.toString() });

           } else {
                return;
           }
       }catch (Exception e){
   return;
       }
      return;

}
