System Information

Question

I'm hoping to pull out certain system values from a windows operating system; xp mainly.
I understand there is bits you can pull out on the fly:
public class Operating
    public static void main(String[] args)
        String name = "os.name";       
        String architecture = "os.arch";
        String version = "os.version";
        String user = "user.name";
            System.out.println(System.getProperty(name));
         System.out.println(System.getProperty(architecture));
         System.out.println(System.getProperty(version));
        System.out.println(System.getProperty(user));   
        System.out.println(System.getenv("COMPUTERNAME"));
           System.out.println(System.getenv("HOMEDRIVE"));
}Ideally though I'm trying to pull out a bit more.
Processor & Installed Physical Memory (RAM)
ie:
Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz, 1995 Mhz, 4 Core(s), 4 Logical Processor(s)
4.00GB
So I thought I could try it a bit differently using
Process child = Runtime.getRuntime().exec(command); of msinfo. It has the option to export that into a text file and then scan that in.
It got messy, either the system didn't recognise the command, it is sometimes "msinfo32" or "winmsd" and I got alot of unknown chars.
Anyways, thanks for your patience with the wall of text, is there a better way for me to approach this?
I hope to nail this to apply the same method to the command "tasklist" and possibly "netstat"

Just something I'm interested in playing round with, I understand it is relatively simple with other languages. I'm intrigued, there must be a decent way to do this in java, No, not really since Java and all APIs are designed to be platform independent, so it's usually hard to get hold of things that are platform dependent.
trying to wrap my head how.
I had considered using JNI but to be honest never used it.
I'm just trying to work out a java option to do this, considering there are windows commands that pull this information, there must be a way for me to extract from a textfile/dos Yes, as you said in your first post. You can execute the commands, and parse the output, but I don't count that as a decent way.
or go down the registry path.That would also require native code, libraries that are native, or executing native commands.
