Creating an IntStream of Random Values

In Java SE 8, class SecureRandom has overloaded methods ints, longs and doubles, which it inherits from class Random (package java.util). These methods return IntStream, LongStream and DoubleStream, respectively, that represent streams of random numbers. Each method has four overloads. We describe the ints overloads here—methods longs and doubles perform the same tasks for streams of long and double values, respectively:

• ints()—creates an IntStream for an infinite stream of random ints. An infinite stream has an unknown number of elements—you use a short-circuiting terminal operation to complete processing on an infinite stream. We’ll use an infinite stream in Chapter 23 to find prime numbers with the ...
