A few things I've noticed:
1.) you don't set myUrl,
you should most likely assign it to the return value of method urlOut
2.) I would not keep more than one line of code in the public static void main
3.) I would name your methods differently and don't see a reason why urlOut is a static method in the launch class while desktopsupport is an instance method in a separate class, besides desktopsupport is not camel-cased
4.) I see one flaw in urlOut immediately, it doesn't detect for
https://; it also wouldn't add a protocoll if
http:// was in the middle of the
String (use startsWith() instead)
5.) urlOut should not evaluate args[], instead args[0] should be passed to it and the size of args should be evaluated before
6.) why do you set bing.com temporarily and google.com as default location?
Considering the size and purpose of your code I would say it's not really important to stick to OOP design, it's more important the code functions correctly and that you consider refactoring if you decide to add a whole lot of new code.
