Here's an example of how to track statistics and the population of a Zone.

There are two built-in Zones, Globals.env.globalZone and
Globals.env.scratchZone, and then you can create others (and Swarms
double as Zones).  In Java, you should be able to find anything from
Swarm you're allocating in a Zone.  The rest will be garbage
collected.

(Note that garbage collection won't ensure you don't have leaks, as you
can mistakenly be accumulating objects in a data structure.)

import swarm.Globals;
import swarm.defobj.ZoneImpl;
import swarm.defobj.Zone;
import swarm.objectbase.SwarmObjectImpl;

public class ShowZone {
    static void main (String args[]) {
        Globals.env.initSwarm ("ShowZone", "0.0", "address@hidden", args);
        
        Zone zone = new ZoneImpl (Globals.env.globalZone);
        new SwarmObjectImpl (zone);

        System.out.println ("statistics");
        Globals.env.xprint (zone);
        System.out.println ("members");
        Globals.env.xfprint (zone);
    }
}
