![]() ![]() In this case IntelliJ IDEA creates a default constructor with no parameters. Using ⌘N, or Alt+Insert, again, we can choose to generate a constructor for this class. ![]() Let’s look at generating new code inside these classes. IntelliJ IDEA creates a Java class file that implements this interface and opens it in the editor. We can enter our own name for the implementation of this interface, let’s say “Fiesta”. If we press Alt+Enter on the interface declaration (to invoke intention actions), IntelliJ IDEA suggests an option to implement this interface. We can continue creating classes from the project window if we want, but it’s often more convenient to do from inside the code. IntelliJ IDEA creates a new Java file with the correct code to declare this as a new interface. IntelliJ IDEA can create a number of different types of classes, including the new Record preview feature in Java 14. Note that if we want to change the code that’s generated here, we can alter the file and code templates. We can invoke New again with the same keyboard shortcut and use it to create a new Java class. IntelliJ IDEA will use the full package declaration to create all the necessary folders to match this package name. ![]() Using ⌘N on MacOS or Alt+Insert on Windows and Linux, in the project window we can create a new package. The goal of the blog is to provide an easy way for people to skim the content quickly if they prefer reading to watching, and to give the reader/watcher code samples and links to additional information.įirst we’ll explore some of the common ways to generate code that we’ve already seen in other videos. This blog post covers the same material as the video. Indeed, in IntelliJ IDEA, we do not have to. Although Java as a language is steadily reducing the amount of boilerplate and typing that developers need to do, there are still plenty of common patterns of code that we simply shouldn’t have to type character by character. Now we’re going to look at Code Generation, which compliments the completion features so nicely that in the past we put both sets of features into a single video.Ĭode Generation is a really helpful feature in IntelliJ IDEA, particularly for Java programmers. A few weeks back we published a blog post and video about Code Completion. ![]()
