How do I execute an external program from Java?

Question

Possible duplicates:

I want to execute a program of Perl from Java.

I take a file name with an argument and carry out a program, and the program of Perl outputs a result file.

So it is the program side of the JAVA

I appoint an argument and carry out Perl program
Perl program reads the file which I spitted out

2) checks the existence of the file and seems to be able to do it, but will 1) be possible? ActivePerl is installed with the present machine. I develop Java on Eclipse.

Please stop calling it "JAVA" - it's not an acronym, the programming language is called "Java". — Jesper

I thought JAVA was a recursive acronym that makes reference to the virtual machine: Java Ain't a Vacuum-tube Appliance. ;) — daotoad

Use:

String command = "ls";    
Runtime.getRuntime().exec(command);

Reference:Executing a Command

FYI: The link contains examples of commands with arguments, and with spaces too.
