Executing System level commands

[Naresh Rajan]

Hi

I am trying to make an installable for my application. All i need to do is copy a set of folders into the folder of the users choice. For the front end i am using Swings.

I will be getting the name of the folder (where the appln has to be copied) from the front end. I need to execute a set of commands that will be copying the folders from the CD to the specified location.

This has to be done on both DOS and UNIX.

How do i execute these system level commands from java???

You execute Windows command prompt or Unix commands by using java.lang.Runtime.exec() - see the API documentation.

If you think at some point you might need to support more than those two platforms, you should copy them yourself using the java.io.File* classes (or java.nio.channels.FileChannel if you want to get fancy). Possibly slower, but insulates you from platform differences.
