Top 3 features of Java 13 and improvement of production and efficiency

Everyone is aware that the pace of development of new updates of the Java programming language was relatively slow, with major changes within a few years. Java changed in 2018 when Oracle revealed a new release strategy. Now Oracle sees many Java updates every year.

The new Java 13 update is a very good example and does not have other major features in Java 13 but provides a much better improvement for all developers and is one of the new features of Java 13 known as CDS Java.

According to the 13 enhancement proposal 350, the better target application of all the features is to make all the users run a trial to make the class list with the improvement of class data sharing. To end the need of

Java 13  JEP 350: Dynamic CDS Archives

 JEP 351: ZGC: Uncommit Unused Memory  JEP 353: Reimplement the Legacy Socket API

JEP 350: Dynamic CDS Archives Dynamic CDS extends all of this application class data sharing that was contributed by all Oracle to OpenJDK 10. It first included in Oracle JDK as a commercial feature and all of it at the end of the execution of any Java application. It allows for a dynamic collection of classes.

Earlier, using AppCDS was one of the most multi-step processes in which to list all related classes. And, generated by the collection to be used for subsequent runs using the list.

JEP 351: ZGC: Uncommit Unused Memory ZGC is the experimental low latency garbage collector introduced in JDK 11.

ZGC's main design did not allow all memory pages to return to the operating system because they not needed when all heaps shrink and for all extended periods of memory time. Unused as in the environment where all resources decorated between many services and this increases the efficiency and efficiency of the system The Imit can be kept.

JEP 353: Reimplement the Legacy Socket API The legacy socket API has reintroduced in JEP 353. Both java.net.Socket and java.net.ServerSocket API are back in implementation in JDK 1.0. All of these API implementations include many technologies. Which makes them hard to keep up with. A new implementation in JDK 13, which provides NioSocketImpl that no longer requires native code, simplifies many platforms to the existing buffer system.

Conclusion Regarding Java 13, I think text block and switch expressions are going to be important for all users, however, it only has preview language features, which is not the default and will not notice EP integrating JDK 13 users. Its users do not want much difference in migrating JDK, in Java 13 there is hope that text box and text Witch expression will be provided and distributed, in this way you can try your features and provide your feedback to JDK developers and you can find the Java application development company for your application and help them.
