As a result, those packages have moved, and this will require changes to package imports. Here, we have used the Google Chrome browser.

Oracle has chosen the Eclipse Foundation as the new home for the Java Platform Enterprise Edition. 1) Open an internet browser on your computer system.

Due to lack of browser support for Java plugins, the Applet API has been deprecated.

The “var” keyword only affects local variables, and the Type Inference keeps you repeating the same text over and over again

A developer-friendly keyword “var” was added to help to reduce boilerplate coding.

This is very interesting for serverless-compute and one-offs in Kubernetes

A REPL (read-eval-print-loop) tool, JShell, was added to support interactive programming, similar to what is available in Python.

Modularization also enables code to be refactored for easier maintenance, through a self-describing collection of code, data, and resources.

The introduction of modularity to better support scaling down to small computing devices.

However, the biggest differences between Java 8 and Java 11 are:

Java Is Still Free 3.0.0 (Oct 2021) by the Java Champions (pillars of the Java community).There are always a lot of little things that go into a release of Java, or any product for that matter.Java Client Roadmap Update, by Oracle, 2020-05.I suggest reading these two white papers: This approach is feasible only where you or your client have control over users’ machines such as a corporate environment, a school, etc. At least two vendors supply versions of their Java runtimes that include the OpenJFX/JavaFX libraries: Azul Systems (ZuluFX), and BellSoft (LibericaFX). Some charge a fee, some do not.īy the way, another option is to build your JavaFX app without a bundled Java runtime, and without the OpenJFX/JavaFX libraries. These vendors include, off the top of my head, Amazon, Azul Systems, Oracle, Microsoft, Adoptium, SAP, BellSoft, Pivotal, Red Hat/IBM, FreeBSD Ports & Packages. You can obtain Java 17 implementations from any of several vendors. If you bundle a Java runtime as discussed above, the JRE is irrelevant as the new modern tooling will include only the parts necessary for your app.

The JRE was just a subset of a JDK, with some of the tools removed. The JRE (Java Runtime Environment) is becoming passé as Oracle no longer expects end users in general to have a Java runtime installed on their systems. So basically there's not a JRE for java 17? If you feel the need and have the nerve, the cutting edge approach is to compile a native app using GraalVM technology from Oracle.

The Java Platform Module System make it possible to strip the Java runtime down to only the parts actually used by your app.

Tool that runs Java files and allows the user to create executables. Modern Java offers the jlink & jpackage tooling to assist with bundling a Java runtime into your app. Suite of tools for properly building apps in the popular format. This way at compile-time you have complete control, so you can compile for Java 17 while also running on Java 17. Bundle a Java runtime within your app.Compile your app for Java 8, if your codebase does not use features from Java 9 and later.Yes, you understand the problem correctly: An app compiled for Java 17 cannot be run on a Java 8 runtime. To my understanding, this error means that my code is compiled with Java 17 but my JRE can run only Java 8 code. When I do that I get this error: : Main has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0Īt 1(Native Method)Īt (ClassLoader.java:756)Īt (SecureClassLoader.java:142)Īt (URLClassLoader.java:473)Īt $100(URLClassLoader.java:74)Īt $1.run(URLClassLoader.java:369)Īt $1.run(URLClassLoader.java:363)Īt (Native Method)Īt (URLClassLoader.java:362)Īt (ClassLoader.java:418)Īt $AppClassLoader.loadClass(Launcher.java:352)Īt (ClassLoader.java:351)Īt (LauncherHelper.java:601)Įrror: A JNI error has occurred, please check your installation and try again After creating the JAR (building the artifact) I try to execute it with the JRE 1.8.0_311.
