Download or read book The Go Programming Language written by Alan A. A. Donovan and published by Addison-Wesley Professional. This book was released on 2015-11-16 with total page 1202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Go Programming Language is the authoritative resource for any programmer who wants to learn Go. It shows how to write clear and idiomatic Go to solve real-world problems. The book does not assume prior knowledge of Go nor experience with any specific language, so you’ll find it accessible whether you’re most comfortable with JavaScript, Ruby, Python, Java, or C++. The first chapter is a tutorial on the basic concepts of Go, introduced through programs for file I/O and text processing, simple graphics, and web clients and servers. Early chapters cover the structural elements of Go programs: syntax, control flow, data types, and the organization of a program into packages, files, and functions. The examples illustrate many packages from the standard library and show how to create new ones of your own. Later chapters explain the package mechanism in more detail, and how to build, test, and maintain projects using the go tool. The chapters on methods and interfaces introduce Go’s unconventional approach to object-oriented programming, in which methods can be declared on any type and interfaces are implicitly satisfied. They explain the key principles of encapsulation, composition, and substitutability using realistic examples. Two chapters on concurrency present in-depth approaches to this increasingly important topic. The first, which covers the basic mechanisms of goroutines and channels, illustrates the style known as communicating sequential processes for which Go is renowned. The second covers more traditional aspects of concurrency with shared variables. These chapters provide a solid foundation for programmers encountering concurrency for the first time. The final two chapters explore lower-level features of Go. One covers the art of metaprogramming using reflection. The other shows how to use the unsafe package to step outside the type system for special situations, and how to use the cgo tool to create Go bindings for C libraries. The book features hundreds of interesting and practical examples of well-written Go code that cover the whole language, its most important packages, and a wide range of applications. Each chapter has exercises to test your understanding and explore extensions and alternatives. Source code is freely available for download from http://gopl.io/ and may be conveniently fetched, built, and installed using the go get command.

Book excerpt: Yet again, another Java book.Nor it is the breaking news, neither we need a break from learning traditional way. There are plenty of good books on Java, written in a traditional way.However, this book breaks some typical patterns of any other Java book written so far.It will not exhibit the same characteristics that start with a distinctive introduction to Java, principles of object oriented programming, Values and Data types, Operators, Input in Java, Library methods, etc. Instead it presents problems for learners to solve and learn from them.This book will empower computer science and programming students to build their applications in Java. It is for the first time that a book with a "problems-solutions-explanations" approach will help you develop logical and analytical thinking so that you can easily solve interactive problems, not only in Java, but also in any programming language. It will not exhibit the same characteristics that start with a distinctive introduction to Java, principles of object oriented programming, Values and Data types, Operators, Input in Java, Library methods, etc. Instead it presents various types of problems for learners with solutions to learn from them.Why? Because, we feel a programming language is more relevant to practice, not to theory. Not only practice makes you perfect, it clears the theoretical concepts as well.Because, we feel a programming language is more relevant to practice, not to theory. Only practice makes you perfect in computer science and programming. We are learning Java to solve problems and build applications, right? To do that, we better start writing code first. If you cannot take a short swim in the pool, you cannot learn swimming. Let us start with small programs, the result follows and since it is caused by some phenomenon, we will learn the theory thereafter.We will study the problem first, then we solve it and practice some more relevant problems. After that we will discuss theory.After all, we want to build an application, which is concrete and reality.Although the Abstraction stays behind the curtain, we will learn them with the help of our problems.As we progress, through the eyes of 100 problems, we will learn the following topics:Chapter One: Java, a High Level Language A Short Note on the Book About this Book Java is a High Level Language High Level to Machine Language Memory allocation, heap and stack Chapter Two: Java Standard Edition Development Kit and IDE Java SE Development kit IntelliJ IDEA 2018.2.4 Community Edition Chapter Three: How Java Programming Works Difference between POP and OOP Java program is written within a class Chapter Four: Objects and Data TypesObjects Share Two Characteristics Variables or Fields in Java Primitive Data Types and more Chapter Five: Variables, the Name of a Field Difference between Variables Chapter Six: Array the Container ObjectAn Array in Disarray What is an Array Apache Commons Lang Java ANT Application Chapter Seven: Operators and Conditional Statements Arithmetic and Unary Operators Equality, and Relational Operators Conditional Operators InstanceOf Operators Control Flow - Part One Chapter Eight: Iterative Constructs, Entry and Exit Controlled Loops Entry Controlled loop: Fixed and Unfixed Iteration For or While, it Depends Chapter Nine: Basic Input and Output in Java Chapter Ten: Classes and Objects, A Brief Introduction Chapter Eleven: Interface and Abstraction Chapter Twelve: Exception Handling Chapter Thirteen: Data Structure, A Brief Introduction What Next

Download or read book Java Concurrency in Practice written by Tim Peierls and published by Pearson Education. This book was released on 2006-05-09 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Threads are a fundamental part of the Java platform. As multicore processors become the norm, using concurrency effectively becomes essential for building high-performance applications. Java SE 5 and 6 are a huge step forward for the development of concurrent applications, with improvements to the Java Virtual Machine to support high-performance, highly scalable concurrent classes and a rich set of new concurrency building blocks. In Java Concurrency in Practice, the creators of these new facilities explain not only how they work and how to use them, but also the motivation and design patterns behind them. However, developing, testing, and debugging multithreaded programs can still be very difficult; it is all too easy to create concurrent programs that appear to work, but fail when it matters most: in production, under heavy load. Java Concurrency in Practice arms readers with both the theoretical underpinnings and concrete techniques for building reliable, scalable, maintainable concurrent applications. Rather than simply offering an inventory of concurrency APIs and mechanisms, it provides design rules, patterns, and mental models that make it easier to build concurrent programs that are both correct and performant. This book covers: Basic concepts of concurrency and thread safety Techniques for building and composing thread-safe classes Using the concurrency building blocks in java.util.concurrent Performance optimization dos and don'ts Testing concurrent programs Advanced topics such as atomic variables, nonblocking algorithms, and the Java Memory Model
