Java 9 Features with Examples

The Java SE 9 Platform Specification will build upon the Java Language Specification, the Java Virtual Machine Specification, and the Java SE APIs defined in Java SE 8. As an Umbrella Platform Specification, this document will specify significant features by reference to other Specifications which are either defined in new Component JSRs or revised in JCP Maintenance Releases of existing such JSRs. This Specification will directly specify smaller features, enhancements, clarifications, and bug fixes that are not part of any Component JSR Specification. The Java Platform, Standard Edition (“Java SE”) is the core Java platform for general-purpose computing.

It can be used to parse ECMAScript code from a string, URL, or file with methods of Parser class. Methods of this class return an object of CompilationUnitTree class, which represents ECMAScript code as an abstract syntax tree. Java added Parser API which allows use to Enable applications, in server-side framework, particular IDEs etc..

Implement Selected ECMAScript 6 Features in Nashorn

The Expert Group will communicate primarily via e-mail, using a publicly-readable mailing list. 2.12 Please describe the anticipated schedule for the development of this java se 9 certification specification. The Java SE platform itself does not have a single package name. All of its requirements are reflected in the packages of its constituent Java SE APIs.

• This API is purely a hint, and carries no semantic behavior requirements.
• This would include potential incorporation of Eclipse MicroProfile technologies into the platform.
• Recommending Java 10 is probably a bad idea if you cannot upgrade to Java 11 immediately when it is out.
• Oracle released two more updates to Java 6 in March and April 2013, which patched some security vulnerabilities.

In this article, we will look into Java 9 features in detail. Older releases, which do not include the most up to date security vulnerability fixes and are no longer recommended for use in production, remain available in the OpenJDK Archive. Only developers and Enterprise administrators should download these releases. The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the JavaTM platform. Master creating pluggable and loosely coupled components or modules, with services, service providers, and service consumers.

Java New Features

Oracle doesn’t look like the bad guy anymore, they’re not going to hold it up and the community can push it as far as they wanna push it. So I think that’s really gonna show how much Oracle planned to invest in Java EE, but I think it’s that beneficial. We’ve seen in the past huge releases containing many, many things and the reason they get pushed out a year, six months, two years, is because largely we have been waiting for different features. So Java 8 was delayed because of lambdas, Java 9 was delayed because of Jigsaw. In fact, Java 8 largely was also delayed because of Jigsaw which was later pulled.

Link time is a phase between the compile and runtime, jlink works there for linking and assemble modules to runtime image. Java 9 has added some new commands to improve the diagnose issues. These diagnostic command are used https://remotemode.net/ to diagnose Hotspot and JDK. This installer allows us to enable and disable web deployement. We can enable web deployment by selecting Custom Setup, install and click on the checkbox from the welcome page of the installer.

Java 18 updates

Recommending Java 10 is probably a bad idea if you cannot upgrade to Java 11 immediately when it is out. Java 8 should remain the recommended version for people who cannot afford to upgrade every 6 months. Apparently in the future Oracle wants to release a LTS version every three years or every 6th release, so the next LTS release to be expected after Java 11 is Java 17 in September 2021.

It does have big benefits in terms of the future of Java, how we can reduce the footprint of Java, how we can develop modules that can be incubated like HTTP/2 and things like that. So it provides a lot of promise, but it’s just not there yet. I think it’s gonna take a long time for the industry and the ecosystem to really embrace modules. We believe that the adoption of Java 9 is gonna be as big as any of the previous releases really.

Java SE 9 and Java EE 8 Released

It is a new kind of Java programing component that can be used to collect Java code . The main goal of this project is to easily scale down application to small devices. In Java 9, JDK itself has divided into set of modules to make it more lightweight.

• Re-watch Cory, James, Gary, and Rain as they share knowledge on how to contribute to open-source projects such as Chocolatey CLI.
• User sites might be left wondering whether they should accommodate such a quick update cycle.
• In Java 9, control panel was rewritten as a JavaFX application and the storage location has changed.
• In Java 9, as long as the inferred type is denotable, we can use the diamond operator when we create an anonymous inner class.
• This is very similar to what many are used to from the Ubuntu release model .
