How to use java to finish the following system command?

[Autumn-Fox]

I want to run the system commands with java in Linux environment.
For example:
" tar -cvf test.tar ./test/* "

"su"

"cp src.txt tgt.txt "

etc.

Runtime.getRuntime().exec("tar -cvf test.tar ./test/*");

If you plan on using Java 5 (1.5), take a look at
java.lang.ProcessBuilder.

You might have trouble if you need to enter a password for the 'su'
command, due to io streams from the process and the jvm. being vague as
can't really remember the specifics from a previous project.
