Java newbie question..

In windows, if I want to start another application from Java-code,
(like notepad.exe or invoke a document c:\mydoc.htm with my
default-browser)
what class/method do I use in Java?

TIA,

hi,
you may use

Process proc = Runtime.getRuntime().exec("notepad.exe");

There is an excellent article on the techniques to use - and some pitfalls
to avoid - in this article:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps_p.html

The author begins by showing you basic approaches that may or may not work
very well, then gradually improves them until he has arrived at fairly
bulletproof ways of executing commands or external programs via Java.
