By: David Cuartielles , Andreas Göransson, Foster-Johnson

Overview of this book

Java is a versatile, popular programming language used across a wide range of industries. Learning how to write effective Java code can take your career to the next level, and The Java Workshop will help you do just that. This book is designed to take the pain out of Java coding and teach you everything you need to know to be productive in building real-world software. The Workshop starts by showing you how to use classes, methods, and the built-in Collections API to manipulate data structures effortlessly. You’ll dive right into learning about object-oriented programming by creating classes and interfaces and making use of inheritance and polymorphism. After learning how to handle exceptions, you’ll study the modules, packages, and libraries that help you organize your code. As you progress, you’ll discover how to connect to external databases and web servers, work with regular expressions, and write unit tests to validate your code. You’ll also be introduced to functional programming and see how to implement it using lambda functions. By the end of this Workshop, you’ll be well-versed with key Java concepts and have the knowledge and confidence to tackle your own ambitious projects with Java.

Summary

It shouldn't matter the order in which different threads act on your data, and you should be able to easily add functionality that doesn't affect older parts of your application. Following these FP concepts allows you to build code that can easily be used in multithreaded applications, as well as to build code that can be tested very easily for problems and regression bugs. It also often makes your code much more readable.

Using the core concepts of FP that you've learned about in this chapter—pure functions and immutability—can lead to performance issues in some cases, specifically when modifying large datasets. There are ways to get around these, as we'll explore in later chapters.

Because Java was designed for an OOP approach, it can be a bit daunting to get into FP at first, but if you "go functional" in only certain parts of your code, the transition from OOP may become easier.

In the next chapter, we'll focus on...
