The following code shows a few examples: (Integer. To print hexadecimal numbers, we could previously use the toHexString() method of the Integer, Long, Float, and Double classes – or String.format(). There is no JDK enhancement proposal for this extension. The following example extracts the bytes of a String by reading its private value field: public class EncapsulationTest) ĪssertThat(duration, is(Duration.ofMillis( 1_750))) This mode allowed access via deep reflection to non-public classes and methods of those JDK class library packages that existed before Java 9 without configuration changes.

Until Java 16, this had little impact on existing code, as the JDK developers provided the so-called 'Relaxed Strong Encapsulation' mode for a transition period. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb). Before Java 16: Relaxed Strong Encapsulation News The JDK is the Java Development Kit, the full-featured SDK for Java. In Java 9, the module system ( Project Jigsaw) was introduced, especially to modularize code better and increase the Java platform's security. In this article, we looked at the news about the new Java 17 version, going through its recent developments, new capabilities, support definition and release cycle process.

Oracle will provide free upgrades for Java 17 for at least. On September 14, 2021, the time had finally come: after the five 'interim versions' Java 12 to 15, each of which was maintained for only half a year, the current Long-Term Support (LTS) release, Java 17, was published. Java 16 also includes enhanced and new preview and incubator features. The Java community can then provide feedback that is taken into account in the further development of the features.

This means that new features can be delivered and tested in a non-final state. With JDK Enhancement Proposal 409, Sealed Classes are declared ready for production in Java 17 without any further changes.) Strongly Encapsulate JDK Internals As mentioned before, the new process targets the next LTS version to be version 21, and the plan is to release it by September 2023. Java 17 Features(with Examples) Sven Woltmann. Since Java 10, a new Java release is published every six months. Three minor changes were published in Java 16. (Sealed classes were first introduced in Java 15 as a preview feature. In our examples, we will see how we use lambdas and streams in the different scenarios. The stream API and lambda expressions are the new features that move us closer to functional programming. With the release of Java 8, this statement became a little less valid. New latest features list: Foreign Functions and Memory API, an alternative to JNI. The big innovation in Java 17 (besides long-term support) is sealed classes (and interfaces).ĭue to the large scope of the topic, you'll read what sealed classes are, how exactly they work, and why we need them in a separate article: Sealed Classes in Java Java was always known for having a lot of boilerplate code.
