Introduction to Programming

By: Nick Samoylov

Overview of this book

Have you ever thought about making your computer do what you want it to do? Do you want to learn to program, but just don't know where to start? Instead of guiding you in the right direction, have other learning resources got you confused with over-explanations? Don't worry. Look no further. Introduction to Programming is here to help. Written by an industry expert who understands the challenges faced by those from a non-programming background, this book takes a gentle, hand-holding approach to introducing you to the world of programming. Beginning with an introduction to what programming is, you'll go on to learn about languages, their syntax, and development environments. With plenty of examples for you to code alongside reading, the book's practical approach will help you to grasp everything it has to offer. More importantly, you'll understand several aspects of application development. As a result, you'll have your very own application running by the end of the book. To help you comprehensively understand Java programming, there are exercises at the end of each chapter to keep things interesting and encourage you to add your own personal touch to the code and, ultimately, your application.

Numeric stream interfaces

As we have mentioned already, all the three numeric interfaces, IntStream, LongStream, and DoubleStream,have methods similar to the methods in the Stream interface, including methods of the Stream.Builder interface. This means that everything we have talked so far in this chapter equally applies to any of the numeric stream interfaces. That is why, in this section, we will only talk about those methods that are not present in the Stream interface:

  • The range(lower,upper) and rangeClosed(lower,upper) methods in the IntStream and LongStream interfaces. They allow us to create a stream from the values in the specified range.
  • The boxed() and mapToObj() intermediate operations, which convert a numeric stream to Stream.
  • The mapToInt(), mapToLong(), and mapToDouble() intermediate operations, which convert a numeric stream of one type to a numeric stream of another...
