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

In this chapter, you have been introduced to two main APIs in the Java language: java.io and java.nio. They have some overlapping functions, and they are needed to deal with streams and files. On top of that, you have seen how to work with sockets, a natural source of data that can only be handled with streams.

There have been a series of examples looking at how to capture data from the terminal, which in the end happened to be stream (System.in). You then explored how to process it using streams with all sorts of high-level functions, such as filter, map, sorted, foreach, reduce, and collect. You have seen how to open files and properties files, and how java.nio is very capable with the former, but not with the latter.

From a more practical perspective, this chapter has introduced one important technique that was only explained in theory in an earlier chapter: how to use finally to close streams, and avoid potential memory issues during runtime. You have seen that, in...
