Environmental Variables in Java Program

Can we pull out the environmental variables and their associated value which
are set in the Operating System to our java program?

eg: in one MS DOS window I set,

set xyz="Just For Testing";
set path="c:\jdk1.2.2\bin;

can I read the value of the above 2 environmental variables in a java program
which I execute in the same window?

I tried, System.getProperties(), It returns only some std env variables...

You can't access all the environment variables from System.getProperty method.
Only thing is you write either a native 'C' program or a batch program which
can take input parameter and prints the value. You can use Runtime class
to execute the shell or exe file and read the output from the Process.
