An introduction to the world of Java programming written for those with a non-programming background. Explains what programming is, programming languages, syntax, development environments, and includes examples of coding for practice along with reading.

Get a solid understanding of Java fundamentals to master programming through a series of practical steps Key Features * Enjoy your first step into the world of programming * Understand what a language is and use its features to build applications * Learn about a wide variety of programming applications Book Description 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. What you will learn * Understand what Java is * Install Java and learn how to run it * Write and execute a Java program * Write and execute the test for your program * Install components and confgure your development environment * Learn and use Java language fundamentals * Learn object-oriented design principles * Master the frequently used Java constructs Who this book is for Introduction to Programming is for anybody who wants to learn programming. All you'll need is a computer, internet connection, and a cup of coffee.

Updated with the latest Maven coordinates, Java programming features, and API changes, this book is your guide to solving problems in writing asynchronous and event-based programs Key Features * Explore a variety of tools and techniques used to solve problems in implementing concurrency and parallelization * Learn about core operators in RxJava that enable you to express your code logic productively * Apply RxJava with Kotlin to create responsive Android apps with better user experience Book Description RxJava is not just a popular library for building asynchronous and event-based applications; it also enables you to create a cleaner and more readable code base. In this book, you'll cover the core fundamentals of reactive programming and learn how to design and implement reactive libraries and applications. Learning RxJava will help you understand how reactive programming works and guide you in writing your first example in reactive code. You'll get to grips with the workings of Observable and Subscriber, and see how they are used in different contexts using real-world use cases. The book will also take you through multicasting and caching to help prevent redundant work with multiple Observers. You'll then learn how to create your own RxJava operators by reusing reactive logic. As you advance, you'll explore effective tools and libraries to test and debug RxJava code. Finally, you'll delve into RxAndroid extensions and use Kotlin features to streamline your Android apps. By the end of this book, you'll become proficient in writing reactive code in Java and Kotlin to build concurrent applications, including Android applications. What you will learn * Discover different ways to create Observables, Observers, and Subscribers * Multicast in order to push data to multiple destinations and cache and replay them * Express RxJava idiomatically with the help of Kotlin features such as extension functions and data classes * Become familiar with various operators available in RxJava to perform common transformations and tasks * Explore RxJava's reactive types, including Flowable, Single, Maybe, and Completable * Demystify Observables and how they express data and events as sequences Who this book is for This book is for Java developers who want to leverage reactive programming to develop more resilient and concurrent applications. If you're an RxJava user looking to get to grips with the latest features and updates in RxJava 3, this book is for you. Fundamental knowledge of core Java features and object-oriented programming will assist you in understanding the key concepts covered in this book.
