How to call another program in java?

[Outy]

Hi,

I have to write an application that gets a message, looks at the first 4 characters of the msg(string). Then my application has to look into a file which other application should be started regarding the 4 ch.
So is there a function in java that can call another application?

Thx

See the java.lang.Runtime class. For example:
Runtime.getRuntime().exec("app_to_start"

Bye, Otto.
