This chapter includes 20 problems that involve date and time. These problems are meant to cover a wide range of topics (converting, formatting, adding, subtracting, defining periods/durations, computing, and so on) via Date, Calendar, LocalDate, LocalTime, LocalDateTime, ZoneDateTime, OffsetDateTime, OffsetTime, Instant, and so on. By the end of this chapter, you will have no problems in shaping date and time, while conforming to your application's needs. The fundamental problems presented in this chapter will be very helpful for obtaining the bigger picture regarding date-time APIs, and will act like the pieces of the puzzle that need to be pieced together in order to resolve complex challenges involving date and time.

Overview of this book
The super-fast evolution of the JDK between versions 8 and 12 has increased the learning curve of modern Java, therefore has increased the time needed for placing developers in the Plateau of Productivity. Its new features and concepts can be adopted to solve a variety of modern-day problems. This book enables you to adopt an objective approach to common problems by explaining the correct practices and decisions with respect to complexity, performance, readability, and more.
Java Coding Problems will help you complete your daily tasks and meet deadlines. You can count on the 300+ applications containing 1,000+ examples in this book to cover the common and fundamental areas of interest: strings, numbers, arrays, collections, data structures, date and time, immutability, type inference, Optional, Java I/O, Java Reflection, functional programming, concurrency and the HTTP Client API. Put your skills on steroids with problems that have been carefully crafted to highlight and cover the core knowledge that is accessed in daily work. In other words (no matter if your task is easy, medium or complex) having this knowledge under your tool belt is a must, not an option.
By the end of this book, you will have gained a strong understanding of Java concepts and have the confidence to develop and choose the right solutions to your problems.
