This connects to the Raspberry Pi and troubleshooting can begin. “crowpi-examples ” does the same, but other optionsĪre selected during the connection, and a debugger is waiting until the application is actually executed. The copied code is then started on the Raspberry Pi. With “crowpi-examples ” the current code is copied to the Raspberry Pi. IP address of your Raspberry Pi to push and run the code from your PC to the Pi. However, there is no need to worry, because most of it is already predefined and all you have to do is enter the These define which parts of the code are executed and how. The CrowPi project uses 3 run configurations. If you are using Jackson 2.12.Now only the start configuration of the project is missing, which is described in the next section. However, depending on the Jackson library version you are using (say, 2.11.3), you might need to annotate the components of your records using the annotation as follows: import .JsonProperty You can add an appropriate annotation to the components of a record, say, as demonstrated in the following gif:ĭevelopers often use third-party libraries like Jackson to persist value objects. In the following example, record Automobile defines one of its components as Engine, another record: If you are working with records but need to transition it to the codebase of an older Java version that doesn’t support records, you can quickly convert a record to a regular class by using the context action Convert record to class or vice-versa by using the context action Convert to a record:Ī record component can be another record. Here’s an example: record Person(String name, int age) Though it helps cut down on boilerplate code significantly, that isn’t the primary reason for its introduction. Records introduce a new type declaration that simplifies the task of modeling your immutable data. You can use this link for a comprehensive list of the new Java 16 features. In this blog post, I will limit coverage of Java 16 to its language features, why you need them, and how you can start using them in IntelliJ IDEA.

I’m personally excited about Java 16! It adds Records and Pattern Matching for instanceof as standard language features with Sealed classes continuing to be a preview feature (in the second preview).įun fact – Records was voted the most popular Java 16 language feature by 1158 developers in this Twitter poll, with Pattern Matching for instanceof second. However, you’ll see these numbers are going to increment at a much faster and predictable rate with Java’s six-month release cadence. If you are still working with Java 8, you might have mixed feelings about the news of the release of Java 16.
