The Java Workshop

4 (2)
By: David Cuartielles, Andreas Göransson, Eric 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.

Relational Database Management Systems

Some of the most common RDBMSes include Oracle, MySQL, SQL Server, PostgreSQL, and DB2. In each case, you have software that runs on a server (or servers) to manage the data, along with separate client software to query and manipulate the data.

To use an RDMS, you first need to install the database software.

Installing a Database

In this chapter, we'll use an open-source database called H2. H2 is written entirely in Java, so you can run it wherever you run a JVM, such as in Windows, Linux, or macOS systems. On account of its portability and simplicity, H2 works well for the database tables we'll create in this chapter.

H2 has some nice features in that it comes with a browser-based database console that you can use to access the database.


H2 can also be used inside your applications as an embedded in-memory database. In this case, the database server and client both exist within your Java application.
