Every random variable has a domain - the set of possible values it can take on. The domain of Total for two dice is the set {2,...,12} and the domain of Die₁ is {1,...,6}. A Boolean random variable has the domain {true, false}.

Method Summary

Modifier and Type	Method and Description
boolean	isFinite()
boolean	isInfinite()
boolean	isOrdered()
int	size()

Method Detail

isFinite

boolean isFinite()

Returns:

true if the Domain is finite, false otherwise (i.e. discrete (like the integers) or continuous (like the reals)).

isInfinite

boolean isInfinite()

Returns:

!isFinite().

size

int size()

Returns:

the size of the Domain, only applicable if isFinite() == true.

isOrdered

boolean isOrdered()

Returns:

true if the domain is ordered, false otherwise. i.e. you can specify 1 object from the domain is < or = another object in the domain.
