Delving into primitive streams
Thus far, all our streams have been for Object types. For example, a Stream<Integer> caters for the wrapper class Integer. Java also has classes specifically tailored for streams of primitives. For example, assuming a stream of int primitives, rather than Stream<Integer>, we use IntStream. As we shall see shortly, primitive streams have some really useful methods for processing numeric data, such as sum() and average().
Table 16.1 introduces the primitive stream classes.
