Summary:

Develop your Java coding skills by exploring object-oriented methodologies, functional programming, software design patterns, and more Purchase of the print or Kindle book includes a free PDF eBook Key Features Get started with programming in Java with this step-by-step guide for experienced programmers Re-enforce your knowledge of object-oriented methodologies applied in Java Develop the range of skills necessary for you to become a successful Java developer Book Description This comprehensive guide will help non-Java developers already using different languages transition from their current language to all things Java. The chapters are designed in a way that re-enforces a developer's existing knowledge of object-oriented methodologies as they apply to Java. This book has been divided into four sections, with each section touching upon different aspects that'll enable your effective transition. The first section helps you get to grips with the Java development environment and the Maven build tool for modern Java applications. In the second section, you'll learn about Java language fundamentals, along with exploring object-oriented programming (OOP) methodologies and functional programming and discovering how to implement software design patterns in Java. The third section shows you how to code in Java on different platforms and helps you get familiar with the challenges faced on these platforms. In the fourth section, you'll find out how you can manage and package your Java code. By the end of this Java programming book, you'll have learned the core concepts of Java that'll help you successfully transition from a different language to Java. What you will learn Gain a solid understanding of the syntax in Java Explore the object-oriented programming basics of the Java language Discover how to implement functions in Java Understand which Java frameworks would be best for solving various problems Explore creational, structural, and behavioral patterns in Java Get to grips with server-side coding in Java Who this book is for This book is for anyone who is currently working with other programming languages and wishes to add Java to their skillset. Prior working experience as a developer using languages other than Java is expected, although no prior knowledge of Java is required.
