DM_NEXTINT_VIA_NEXTDOUBLE

Dm: Use the nextInt method of Random rather than nextDouble to generate a random integer (DM_NEXTINT_VIA_NEXTDOUBLE)
If r is a java.util.Random, you can generate a random number from 0 to n-1
using r.nextInt(n), rather than using (int)(r.nextDouble() * n).

The argument to nextInt must be positive. If, for example, you want to generate a random
value from -99 to 0, use -r.nextInt(100).
