It's intentional. If you just want some fairly pseudo-random numbers,
Math.random works fine (it seeds with System.currentTimeMillis()). If
you want more control, use java.util.Random -- one of its constructors
allows you to specify the seed of your choice. This is especially
useful for testing (use the same specific seed), but is also used when
you need to use a more random seed for tighter security.
