Return Program Results

I am writing a program using ImageMagick and I had one quick question. 
The first step in my scaling process is to get the width and height of 
the image. I have successfully done this on the command line using the 
following command:

         /usr/local/bin/identify -format "%w" 
/Users/lopatins/Desktop/image.jpg

The above command will return the width of the file. I am running 
commands successfully using:

             Process process = Runtime.getRuntime().exec(command);

Where command equals the string to run.

What I don't know is how to return the output from the command line to 
a String variable that I can use in my program. Do you know how to pull 
the output of the program back into WebObjects?

Thanks very much in advance for any help you can provide.

Thanks,
Scott
