### 2.2 Finite domains

In the previous section, we have defined FDVs with domains without considering domain
representation. JaCoP default domain (cllaed IntervalDomain) is represented as an ordered
list of intervals. Each interval is represented by a pair of integers denoting the minimal
and the maximal value. This representation makes it possible to define all possible
finite domains of integers but it is not always computationally efficient. For some
problems other representations might be more computationally efficient. Therefore,
JaCoP also offers domain that is restricted to represent only one interval with its
minimal and maximal value. This domain is called BoundDomain and can be used by a
finite domain variable in a same way as interval domain. The only difference is that
any attempt to remove values from inside the interval of this domain will have no
effect.

The following code creates variable v with bound domain 1..10.

IntVar v = new IntVar(s, "v", new BoundDomain(1, 10) );
