Execute operatingsystem commands from Java classes?

[Egil Poma]

How can I execute operatingsystem commands from my Java classes?

So that I on a Linux box could i.e. execute "ls -l" etc.

Class: java.lang.Runtime
Methods: exec( /*various parameters*/ ):

Example: Runtime.getRuntime().exec( "myprog.exe" );

To answer your question less literally, you can use the java.io.File class to list the files in a directory using the list() and related methods.
