17.3 IntStream Operations
[This section demonstrates how lambdas and streams can be used to simplify programming tasks that you learned in Chapter 7, Arrays and ArrayLists.]
Figure 17.5 demonstrates operations on an IntStream (package java.util.stream)—a specialized stream for manipulating int values. The techniques shown in this example also apply to LongStream
s and DoubleStream
s for long and double values, respectively.
