The new features delivered in Java 16 are: Language Enhancements First Introduced in JDK 14, Finalized in JDK 16 The Java 16 release is the result of industry-wide development involving open review, weekly builds and extensive collaboration between Oracle engineers and members of the worldwide Java developer community via the OpenJDK Community and the Java Community Process. This process has not only given Java developers the opportunity to experiment with these features before they were finalized, but also incorporated that critical feedback which has resulted in two rock-solid JEPs that truly meet the needs of the community.” “Pattern Matching and Records were introduced a year ago as part of JDK 14 and have since gone through multiple rounds of community feedback based on real-world applications.

“The power of the six-month release cadence was on full display with the latest release,” Georges Saab, vice president of development, Java Platform Group, Oracle. This offers a steady stream of innovations while also delivering continued performance, stability and security improvements, increasing Java’s pervasiveness across organizations and industries of all sizes. Oracle delivers Java updates every six months to provide developers with a predictable release schedule.
Additionally, developers can use the new Packaging Tool (JEP 392) to ship self-contained Java applications, as well as explore three incubating features, the Vector API (JEP 338), the Foreign Linker API (JEP 389), and the Foreign-Memory Access API (JEP 389), and one preview feature, Sealed Classes (JEP 397). The latest Java Development Kit (JDK) finalized Pattern Matching for instanceof (JEP 394) and Records (JEP 395), language enhancements that were first previewed in Java 14. If you are using Jackson 2.12.Today Oracle announced the availability of Java 16 (Oracle JDK 16), including 17 new enhancements to the platform that will further improve developer productivity.
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.
