swarm lib

[Cindy Chen]

Hello,

I am Cindy from UCSF.
I have been working on my own simple swarm progams.  I am confused in using 
some swarm lib(Java). I wrote a simple program below (it works if I use only 
Java lib and Java codes):
----------------------------------------
import swarm.collections.String;
import swarm.collections.StringImpl;

class test
{
        public static void main (String args[])
        {
                test bug=new test();
        }
        public test()
        {
                String s=new StringImpl();
                s.catC("abc");
                }
}
-----------------------------------------
There is no compile error. When running it shows:failed to locate native 
function swarm/random/uniformintegerDistImpl.getIntegerMin()I. What do I 
miss out?
Each package has 2 parts: interfaces and Implementing Classes.  I wonder 
what *Impl do. Interfaces are classes and within one interface there are 
some methods. How can I get the interface implemented and use the methods?

Please advice me.
Thanks. I appreciate your help.
Cindy
