Java application development is among the most widely used and widely used languages which require development tools such as JDK. This JDK includes Java Runtime Environment, Java compiler, and the Java APIs.

Java Web Development is comparatively easy for both new as well as experienced users, to begin with.

On 17th September 2019, Oracle preponed the release of a significant update to some featured update. JDK 13 was released globally.

The Most Recent release includes the following features:

JEP-350: Dynamic CDS Archives: To enable dynamic archiving of classes at the end of a Java Program Execution, program class-data sharing is now permitted. The courses being archived will consist of preloaded application and library classes which are currently not covered in the default base-layer CDS archive.

JEP-351: ZGC: Uncommit Unused Memory: This really means to Improve the ZGC to come back unused heap memory back into the Operating System.
Presently, ZGC does not commit and return memory to the operating system irrespective of the previous time usage. This is not optimum for all sorts of programs and or surroundings where memory utilization is a major concern.

JEP-353: Reimplement the Legacy Socket API: Currently the execution used from the java.net.Socket and java.net.ServerSocket APIs are now not easy to debug and maintain user-thread style.
Replacing the underlying execution using a more easy and more efficient with one that isn’t difficult to operate in user-thread mode shall help Java Developers to simplify their job.

JEP-354: Switch Expressions (Preview): The switch expression shall be extended so that it may be used as a statement or a saying. Additionally, both kinds can now use either a traditional case…: labels (with fall through) or a new case… -> labels (without a drop-through), together with a new statement for creating value from a change saying.

The main reason for these modifications is to simplify regular apps development and make it more efficient.

JEP-355: Text Blocks (Preview): Ultimately, Oracle has decided to incorporate text blocks into the Java Language. A text block in Java is a multi-line string expression which reduces the redundant code for escape sequences, automatically formats the series in a predictable way and gives the developer control over format as and if demanded.
