Starting other Applications with Java

Is it possible to start开发者_如何学Go other application that are installed on the system with my java app and pass a file as a parameter to them? I have a client which receives videos from a server and I want my client program to start, lets say the VLC player with the file that I received. How do I manage to do that?

Use Desktop#open(). It will launch the platform default associated application to open the given file.

File file = new File("/absolute/path/to/file.vlc");
Desktop.getDesktop().open(file);

No need to hassle with Runtime#exec() or ProcessBuilder for which you would have to add platform detection and to write platform specific logics for.

Quite simply:

Runtime.getRuntime().exec("vlc [arguments]"); //Write all arguments as you would in your shell.

Make sure you catch all relevant exceptions

You can call the exec method on the Runtime object.

Runtime.getRuntime().exec("System specific command line text here");

You can run an external program pretty easily on Java 5+ with ProcessBuilder, including passing arguments and handling input/output streams.

eg.

ProcessBuilder movieProcess = new ProcessBuilder("/path/to/movieplayer", "/path/to.moviefile");
movieProcess.start();

Only used it myself executing non-UI stuff, I'll give it a quick go and see what happens with something like VLC.

Update - works a treat for flv on Ubuntu, UI is visible and accepts file arguments.
