To run and develop an application in Java, you need to install the Java Development Kit (JDK). There are two different implementations of JDK – OpenJDK and Oracle JDK.

• OpenJDK is the free, open-source version of Java, available under the GPL v2 license.
• Oracle JDK is a paid, full-featured, Java software-package.

In this guide, learn how to install Java on a CentOS 8 server, including the OpenJDK and the Oracle JDK implementation.

• A system with CentOS 8 installed
• A user account with sudo or root privileges
• Access to a terminal window / command line (Search > terminal)
• An Oracle account (only required for Java JDK)

Open JDK is the free version of Java that consists of the Java Runtime Environment (JRE) and Development Tools. To run and develop Java applications, you need to install the complete package with its development kit.

Currently, there are two LTS versions of OpenJDK – OpenJDK 8 and OpenJDK 11. Oracle supports and updates both versions regularly. Although new releases come out every six months, they are maintained only until the next release. Therefore, it is not advisable to install anything other than version 8 or version 11 unless you have a good reason to do so.

Note: You can have more than one version of Java installed on your system. That's helpful if you’re working on different projects that require different Java versions. Such configuration requires you specify the Java environment each time you work on a project.

Open a terminal window and enter the following:

Confirm any prompts, allow the process to finish, and verify the installation with:

To install the older LTS version, OpenJDK 8, use the following command:

Verify Java version 8 is now installed with:

If you are not developing in Java, but still need to run Java applications, you can skip installing the JDK and set up the Java Runtime Environment (JRE).

JRE is a combination of a Java Virtual Machine (JVM) and the libraries required for executing the code in runtime. It is the minimum requirement for running any Java application.

Just like with the Development Kit, there are two LTS versions of the Runtime Environment – JRE 8 and JRE 11.

To install JRE 11, run:

To install JRE 8, use the command:

Note: Remember - You don't need to install OpenJRE if you already have OpenJDK. The Runtime Environment comes with the Java Development Kit by default.

Another alternative to OpenJDK is only installing the headlessversion.

Just like OpenJRE, Java headlessis part of OpenJDK and should not be installed on top of it.

The headless option is a minimal runtime environment, without a graphical interface, more suitable for server applications. It uses minimal system resources and doesn’t include keyboard or mouse support.

Install OpenJDK 11 headlessby entering the following:

For OpenJDK 8 headlessrun:

When installing Oracle Java on CentOS 8, make sure to download directly from the official source, Oracle. This requires creating an account on the Oracle website.

1. Open a web browser and navigate to the Oracle download page. Here you will find all the Java download links for different versions of Java SE.

Note: Java SE is the Standard Edition of the software, mainly used for developing portable desktop apps. An alternative to Java SE is Java Enterprise Edition (Java EE), more suitable for enterprise-level development.

2. Scroll down to see different versions of Java SE and find the one you need. In this article, we are sticking to the LTS release – Java 11.

Jdk-8u151-macosx-x64.dmg

The Java SE 11.0.5 (LTS) section includes a download button to install Oracle JDK (Java Development Kit). Unlike in the previous versions, this edition doesn’t offer the possibility to download Oracle JRE (Java Runtime Environment) as a separate package.

3. Click the blue Download button on the right, just below the Oracle JDK heading.

4. The link takes you to the next page of the download section and informs you about the Oracle JDK License Update. Make sure to review it before you download the software.

5. Scroll down and find the gray box labeled Java SE Development Kit 11.0.5. In it, you will find all the available packages for the software.

6. To download any of the packages, you first need to check the box that confirms you Accept License Agreement.

7. For CentOS 8, the Linux x64 .rpm file is a good package choice since it is easier to install. If you’re running a 32-bit operating system, use Linux x86.

8. To gain access to the file, log in with your Oracle account.

Digital counter remote master user manual. 9. Allow the download to finish. Once it’s complete, open the terminal and enter the following:

Note: Replace userwith the actual username. Additionally, if your filename is different, use the filename of your download.

9. Once the installation finishes, you can check the Java version with the following:

You might have 2 different versions of Java on your system. To set one as the default , use the command:

The system displays a list of different Java versions. If you like the default, press Enter.

If you want to change it, type the number of the version you want, then press Enter.

With the default version set, you can configure JAVA_HOME on your CentOS 8.

By doing so, applications compiled in this programming language can easily access Java’s installation path.

How you define the JAVA_HOME environment depends on which version of Java you have. To define the location of Java 8 or Java 11, refer to phoenixNAP’s instructional guide on How to Set JAVA_HOME Environment Variable.

You should now have one (or more) versions of Java running on CentOS 8.

REmember, if you only need support for running Java applications, choose JRE (Java Runtime Environment). Install JDK (Java Developer Kit) if you need to create Java applications.

This page describes how to install and uninstall JDK 8 for OS X computers.

This page has these topics:

See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.

See 'OS X Platform Install FAQ' for general information about installing JDK 8 on OS X.

System Requirements

Observe the following requirements:

• Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.

• Administrator privileges.

Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.

Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.

JDK Installation Instructions

When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Depending on your processor, the downloaded file has one of the following names:

• jdk-8uversion-macosx-amd64.dmg

• jdk-8uversion-macosx-x64.dmg

Where version is 6 or later.

1. Download the file.

   Before the file can be downloaded, you must accept the license agreement.

2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.

   A Finder window appears containing an icon of an open box and the name of the .pkg file.

3. Double click the package icon to launch the Install app.

   The Install app displays the Introduction window.

   
   

   Note: In some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the Continue button.

   
   

4. Click Continue.

   The Installation Type window appears.

5. Click Install.

   A window appears that says 'Installer is trying to install new software. Type your password to allow this.'

6. Enter the Administrator login and password and click Install Software.

   The software is installed and a confirmation window appears.

7. Refer to http://www.oracle.com/technetwork/java/javase/downloads/jdk-for-mac-readme-1564562.html for more information about the installation.

8. After the software is installed, delete the .dmg file if you want to save disk space.

Determining the Default Version of the JDK

If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.

There can be multiple JDKs installed on a system, as many as you wish.

When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. For example:

To run a different version of Java, either specify the full path, or use the java_home tool:

For more information, see the java_home(1) man page.

Uninstalling the JDK

To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.

For example, to uninstall 8u6:

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
