Think Java: How to Think Like a Computer Scientist

Think Java: How to Think Like a Computer Scientist

Currently used at many colleges, universities, and high schools, this hands-on introduction to computer science is ideal for people with little or no programming experience. The goal of this concise book is not just to teach you Java, but to help you think like a computer scientist. You’ll learn how to program—a useful skill by itself—but you’ll also discover how to use programming as a means to an end.

Authors Allen Downey and Chris Mayfield start with the most basic concepts and gradually move into topics that are more complex, such as recursion and object-oriented programming. Each brief chapter covers the material for one week of a college course and includes exercises to help you practice what you’ve learned.

• Learn one concept at a time: tackle complex topics in a series of small steps with examples
• Understand how to formulate problems, think creatively about solutions, and write programs clearly and accurately
• Determine which development techniques work best for you, and practice the important skill of debugging
• Learn relationships among input and output, decisions and loops, classes and methods, strings and arrays
• Work on exercises involving word games, graphics, puzzles, and playing cards

Free book by O'Reilly - Introducing Java 8: A Quick-Start Guide to Lambdas and Streams

Introducing Java 8
A Quick-Start Guide to Lambdas and Streams
By Raoul-Gabriel Urma
Publisher: O'Reilly
Released: August 2015

Java SE 8 is perhaps the largest change to Java in its history, led by its flagship feature—lambda expressions. If you’re an experienced developer looking to adopt Java 8 at work, this short guide will walk you through all of the major changes before taking a deep dive into lambda expressions and Java 8’s other big feature: the Streams API.

Author Raoul-Gabriel Urma explains how improved code readability and support for multicore processors were the prime movers behind Java 8 features. He’ll quickly get you up to speed on new classes including CompleteableFuture and Optional, along with enhanced interfaces and the new Date and Time API. You’ll also:

• Understand why lambda expressions are considered a kind of anonymous function
• Learn how lambda expressions and the behavior parameterization pattern let you write flexible and concise code
• Discover various operations and data processing patterns possible when using the Streams API
• Use Collector recipes to write queries that are more sophisticated
• Consider factors such as data size and the number of cores available when using streams in parallel
• Work with a practical refactoring example to bring lambda expressions and streams into focus

Raoul-Gabriel Urma is co-author of the bestselling book Java 8 in Action (Manning). He has worked as a software engineer for Oracle’s Java Platform Group, as well as for Google’s Python team, eBay and Goldman Sachs. An instructor and frequent conference speaker, he’s currently completing a PhD in Computer Science at the University of Cambridge.

FREE Ebook from O'Reilly - Modern Java EE Design Patterns

Modern Java EE Design Patterns
Building Scalable Architecture for Sustainable Enterprise Development
Publisher: O'Reilly

With the ascent of DevOps, microservices, containers, and cloud-based development platforms, the gap between state-of-the-art solutions and the technology that enterprises typically support has greatly increased. But as Markus Eisele explains in this O’Reilly report, some enterprises are now looking to bridge that gap by building microservice-based architectures on top of Java EE.

Can it be done? Is it even a good idea? Eisele thoroughly explores the possibility and provides savvy advice for enterprises that want to move ahead. The issue is complex: Java EE wasn’t built with the distributed application approach in mind, but rather as one monolithic server runtime or cluster hosting many different applications. If you’re part of an enterprise development team investigating the use of microservices with Java EE, this book will help you:

• Understand the challenges of starting a greenfield development vs tearing apart an existing brownfield application into services
  Examine your business domain to see if microservices would be a good fit
• Explore best practices for automation, high availability, data separation, and performance
• Align your development teams around business capabilities and responsibilities
• Inspect design patterns such as aggregator, proxy, pipeline, or shared resources to model service interactions

Markus Eisele is a Developer Advocate at Red Hat and focuses on JBoss Middleware. He has been working with Java EE servers from different vendors for more than 14 years, and has worked with different customers on all kinds of Java EE related applications and solutions. He is a prolific blogger, writer, and tech editor for Java EE content. Markus is also a Java Champion and former ACE Director.

Learning Network Programming with Java

Learning Network Programming with Java
Key Features

• Learn to deliver superior server-to-server communication through the networking channels
• Gain expertise of the networking features of your own applications to support various network architectures such as client/server and peer-to-peer
• Explore the issues that impact scalability, affect security, and allow applications to work in a heterogeneous environment

Book Description
Network-aware applications are becoming more prevalent and play an ever-increasing role in the world today. Connecting and using an Internet-based service is a frequent requirement for many applications. Java provides numerous classes that have evolved over the years to meet evolving network needs. These range from low-level socket and IP-based approaches to those encapsulated in software services.

This book explores how Java supports networks, starting with the basics and then advancing to more complex topics. An overview of each relevant network technology is presented followed by detailed examples of how to use Java to support these technologies.

We start with the basics of networking and then explore how Java supports the development of client/server and peer-to-peer applications. The NIO packages are examined as well as multitasking and how network applications can address practical issues such as security.

A discussion on networking concepts will put many network issues into perspective and let you focus on the appropriate technology for the problem at hand. The examples used will provide a good starting point to develop similar capabilities for many of your network needs.

What you will learn

• Connect to other applications using sockets
• Use channels and buffers to enhance communication between applications
• Access network services and develop client/server applications
• Explore the critical elements of peer-to-peer applications and current technologies available
• Use UDP to perform multicasting
• Address scalability through the use of core and advanced threading techniques
• Incorporate techniques into an application to make it more secure
• Configure and address interoperability issues to enable your applications to work in a heterogeneous environment

FREE ebook - Java Application Development on Linux

“Java™ Application Development on Linux®”

is the hands-on guide to the full Java application development lifecycle on Linux.

Linux is the fastest-growing Java development platform because it saves money and time by serving as a platform for both development and deployment. But developers face significant platform-specific challenges and opportunities when managing and deploying Java applicaitons in a controlled production environment.

After a simple command-line application introduces basic tools this program leads readers through business-logic object analysis, database design, Java servlet UIs, Java ServerPages (JSP) UISs, Swing GUIs, and Standard Widget Toolkit (SWT) GUIs. Scaling up to the enterprise level provides the opportunity to use both the JBoss Application Server and the Apache Geronimo Application Server, and Enterprise JavaBeans (EJB).
