What you should know - Java Tutorial

- [Presenter] Before we dive into the details of how to migrate Java applications, let's talk a bit about what you should know before taking the course. This course is primarily for developers that want to understand recent changes surrounding the Java programming language and how their systems will be impacted by them. The lessons in the course will quickly get you up to speed with the current state of the language and teach you strategies for migrating older Java applications to newer versions. This information will primarily benefit individuals responsible for maintaining Java applications or planning the life cycle of an organization's Java-based portfolio. To get the most out of this course, you should have some previous Java experience. You do not need to be an expert but this course shouldn't be your first exposure to the language. Additionally, you should be comfortable managing multiple versions of Java on your workstation. I can walk you through these examples on Windows but if you choose to use another operating system you should understand how to configure multiple JDKs on that system. Finally, a general understanding of new language features introduced in Java 9 and 10 will help you throughout the course. We will not be covering these features in depth in the course but I will touch on them as we look at new features introduced in Java 11, 12, 13 and 14. If you need a refresher, there are some great courses on the LinkedIn learning platform that covered the features introduced in Java 9 and 10. To follow along in the course, you will need several technologies on your workstation. The course uses multiple versions of Java and at various points will require you to have Java 8, Java 11 and Java 14 installed. When we explore the new language features in Java 11 through 14, I'll be using Java 14 the entire time since it contains all of the previous versions language features. When we dive into migrating an application will start in Java 8 and then transitioned to Java 11. I'll be sure to note these versions throughout the course. I use eclipse for my day to day development and in the course, however, you can use the IDE of your preference. The only requirement for an IDE is that it has support for Java 14. Since Java 14 has just recently been released, I had to add the Java 14 support for eclipse plugin to my eclipse installation. Depending upon when you take the course, this may or may not be required. Some of the examples in the course we'll be using Maven so you will need it installed on your workstation. Additionally, if you want to follow along with every step of the course, you'll need Jenkins installed but it is only used for a brief period of time in one of the lessons so it may not be worth the trouble. Finally, feel free to use whatever operating system you're comfortable with. I'll be using Windows but any operating system will work. That is all you need to know to complete the course. I'll guide you through the rest.
