Sure, see below.

That's not a bad approach, since it gives you complete control if you
have several random steams you want to control for debugging purposes.
import swarm.Globals;
public class TestSetSeed {
static void main (String args[]) {
Globals.env.initSwarm ("TestSetSeed", "0.0", "address@hidden",
args);
Globals.env.randomGenerator.setStateFromSeed (1);
double val =
Globals.env.uniformDblRand.getDoubleWithMin$withMax (0.0, 1.0);
System.out.println (val);
}
}
