OpenJDK is completely open source with a GNU General Public License. The main difference between OpenJdk and OracleJDK is licensing. OracleJDK: This article is based on the "OracleJDK" ) (due to legacy), which is free for personal and development use but no longer free for commercial use.Popular OpenJDK builds includes Azul Zulu, Red Hat OpenJDK (IcedTea), Amazon Corretto, Eclipse Adoptium's Temurin, SapMachine, Microsoft OpenJDK, and more. It does not include web-browser plugin and Web Start. OpenJDK includes the virtual machine (HotSpot), the Java Class Library, and the Java Compiler. OpenJDK: Currently, the "OpenJDK" ) developed by Oracle, Java community, Red Hat, Azul Systems, IBM, Microsoft, Amazon, Apple, SAP, provides a free and open-source Java Platform Standard Edition (or Java SE or JDK) official reference implementation.As a result, those packages have moved, and this will require changes to package imports.The Java Development Kit (JDK), officially named "Java Platform Standard Edition" or "Java SE", is needed for writing and running Java programs.
Oracle has chosen the Eclipse Foundation as the new home for the Java Platform Enterprise Edition.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: There are always a lot of little things that go into a release of Java, or any product for that matter.
