Constants? You mean variables that don't change and are final? Same copy of which lasts all throughout, i.e. are static? And they can also be publicly accessible.

public class MaxUnits {
   public static final int MAX_UNITS = 25;
}

I think I understand what you mean, but more detail would have been useful.

static final Request MY_REQUEST_CONST = someRequest;
static final char MY_A_CONST = 'a';
static final int MY_INT_CONST = 20;

list.loadRequestParms(MY_REQUEST_CONST, MY_A_CONST, MY_INT_CONST);

Some things to note. A constant in Java is created by the final static keywords. Convention suggests that constant variable names are uppercase.
