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 short chapter, you were introduced to the Process class in Java. You got to see how a process that outputs to System.out can be captured in the parent program. At the same time, you also saw how the parent can easily send data to the child. The examples showed that it is possible to launch not just your own programs, but also any other program, such as a web browser. The possibilities for building software automation with programs that include the Process API are endless.

We also saw the importance of streams in terms of intra-process communication. Basically, you have to create streams on top of streams to develop more complex data structures, which will allow the code to run a lot faster. The next chapter will cover regular expressions.
