About Upgrading to Java 11 for VS Code for Java

Since the introduction of Java 11 requirement for running VS Code for Java, we have constantly heard from our users that they thought Java 8 is no longer supported, which is NOT true. In this blog, we will explain the requirement itself and provide steps for you to upgrade smoothly and quickly without impact your project.

Clarification of Java 11 requirement

First of all, Java 11 as minimum version of JDK is a requirement only for running VS Code for Java, and to be more specific, it’s a requirement for running the Language Server for Java extension. This is NOT a requirement to your project. That means, you can continue developing your project with version 1.5 or above. Behind scene, JDKs for your project and for running VS Code for Java are specified by configurations of java.configuration.runtimes and java.home respectively. Our Configure JDK document provides more details.

How to upgrade

For a smooth and quick upgrade to Java 11 for running VS Code for Java, here are steps we suggest you follow:

1. Download and install a Java 11 JDK, if haven’t.

2. Open VS Code and open File> Preferences > Settings menu. A Settings view will be launched in your editor window.

3. In Settings view, search for configuration “java.home”, set its value to the root of your JDK 11’s installation path, and save.

5. Restart VS Code, and now you are set to go.

Hope the information we are providing in this blog can help you smoothly and quickly upgrade to Java 11 for running VS Code for Java, while you can continue working with a different version of JDK for your project.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Going Beyond Java 8: Local Variable Type Inference (var) - DZone Java

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.

What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word var has on other pre-existing characteristics.
