Developing Applications with IntelliJ IDEA (The Course)
Course Info
This course includes 3 attempts.
This is a hands-on course based on Part III of the book Getting to Know IntelliJ IDEA. This course will take you through tutorials to show you exactly where your fingers need to be in order to get the most out of using IntelliJ IDEA to build real-world applications. We assume you already have a good handle on the basics of writing code. If you need to build these skills or want a refresher, look at our Working With Code in IntelliJ IDEA course.
This course is a great way to learn how best to use the New UI in IntelliJ IDEA.
In Developing Applications with IntelliJ IDEA you'll learn:
- The options for opening different types of projects, including getting them from a version control server.
- Different ways to run an application inside IntelliJ IDEA, so you can pick an approach that works for your workflow.
- How IntelliJ IDEA's debugger can help you see an application's state - and how it changes - while it's running.
- How to use tests to drive the design and implementation of a small application, and see how IntelliJ IDEA helps you to write correct code.
- The best way to combine automated tests with debugging to troubleshoot problems without having to debug the whole application.
- How to add a new dependency to your project, so you can use external libraries.
- Using build tools such as Maven or Gradle with your project.
- The easiest way to use a version control system like Git with IntelliJ IDEA to track versions of your project code.
