Java is a popular object-oriented programming language used for building applications.

Java Development Kit is the official, reliable, and trustworthy development kit for Java programming. It has been developed by Oracle and is used by programmers around the world. Simply put, JDK combines a wide range of tools and software required to debug, run, and compile apps and applets designed with the Java programming language.

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. /download-insidious-movie-in-hindi-for-mobile.html.

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:

/quickbooks-pro-2013-free-download-full-version-for-mac.html. 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.

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.

9. Allow the download to finish. Once it’s complete, open the terminal and enter the following:

Jdk-8u162-macosx-x64.dmg Download

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.

In general, your system will be more stable for longer if you choose a LTS (Long-Term Support) version.

System Requirements for Installing the JDK on 64-Bit Windows Platform

For supported processors and browsers, see Oracle JDK Certified Systems Configurations.

JDK Installation Instruction Notation for Windows

For any text in this document that contains the following notation, you must substitute the appropriate update version number:

interim.update.patch

For example, if you are downloading the JDK installer for 64-bit systems for update 11 Interim 0, Update 0, and Patch 0, then the file name jdk-11.interim.update.patch_windows-x64_bin.exe becomes jdk-11_windows-x64_bin.exe.

JDK Installation Instructions for Windows

You run a self-installing executable file to unpack and install the JDK on Windows computers.

Install JDK on Windows computers by performing the actions described in the following topics:

Downloading the JDK Installer

Access Java SE Downloads page and click Accept License Agreement. Under the Download menu, click the Download link that corresponds to the .exe for your version of Windows.

Download the file jdk-11.interim.update.patch_windows-x64_bin.exe.

Note:

Verify the successful completion of file download by comparing the file size on the download page and your local drive. Alternatively, you can ensure that the downloaded file's checksum matches the one provided on the Java SE Downloads page.

Running the JDK Installer

1. Start the JDK 11 installer by double-clicking the installer's icon or file name in the download location.
2. Follow the instructions provided by the Installation wizard.
3. After the installation is complete, delete the downloaded file to recover the disk space.

Installing the JDK Silently

Instead of double-clicking or opening the JDK installer, you can perform a silent, non interactive, JDK installation by using command-line arguments.

The following table lists example installation scenarios and the commands required to perform them. The notation jdk stands for the downloaded installer file base name, such as jdk-11_windows-x64_bin.exe.

Installation Scenario	Command
Install JDK in silent mode.
Install development tools and source code in silent mode.

Setting the PATH Environment Variable

It is useful to set the PATH variable permanently for JDK 11 so that it is persistent after rebooting.

If you do not set the PATH variable, then you must specify the full path to the executable file every time that you run it. For example:

1. Select Control Panel and then System.
2. Click Advanced and then Environment Variables.
3. Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.

   Note:

   The PATH environment variable is a series of directories separated by semicolons (;) and is not case-sensitive. Microsoft Windows looks for programs in the PATH directories in order, from left to right.

   You should only have one bin directory for a JDK in the path at a time. Those following the first instance are ignored.

   If you are not sure where to add the JDK path, append it.

   The new path takes effect in each new command window that you open after setting the PATH variable.

   The following is a typical value for the PATH variable:

Beginning to Use the JDK

Use the Java Development Kit in the Windows Start menu to access information related to Reference Documentation.

During JDK install, Java menu items are added to the Windows Start menu to provide easy access to Reference Documentation, which is online documentation web page.

During JDK installation and uninstallation processes, the appropriate start menu items are updated so that they are associated with the latest JDK version on the system

Note:

The Windows 7 and Windows 10 have a Start menu; however, the menu is not available in Windows 8 and Windows 8.1. The JDK and Java information in Windows 8 and Windows 8.1 is available in the following Start directory: %ALLUSERSPROFILE%MicrosoftWindowsStart MenuPrograms.

Uninstalling the JDK on Windows

Uninstalling the JDK in Silent Mode

You can use the command line for uninstalling the JDK.

Use the following command to uninstall the JDK in silent mode:

For example, to uninstall JDK 11, run the command:

To find the UninstallString, see Finding the JDK Registry Key and UninstallString Value .

• This command can be run from anywhere.
• The msiexec.exe executable is located in the windows system directory.
• A reboot is required only if some files are in use during uninstallation; it is not necessary everytime. However, to manually suppress reboot while uninstalling, append REBOOT=R option to the command.
• Append /l “C:<path>setup.log” option to the command if you want to create a log file describing the uninstallation status.

Windows Installer dialog appears prompting you for confirmation. Click Yes to uninstall JDK.

Finding the JDK Registry Key and UninstallString Value

1. Go to Start and type Regedit.
2. In the Registry Editor, go to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Uninstall.

   Under the Uninstall folder, you will find many registry entries within curly brackets.

3. Click Edit and then Find.

   Note:

   Highlight Uninstall folder before performing search for a particular registry.
4. Enter version string as value to find corresponding registry key. For example, enter jdk-11.

   The registry key is highlighted on the right-hand side of the pane and values of various uninstall strings are displayed on the left-hand pane.

5. Note the value of the UninstallString.

The associated bug number is 4895647.

Cleanup the Registry After a Failed JDK Uninstall

Sometimes, attempts to uninstall JDK through the Windows Add/Remove program leave behind some Java entries in the registry that are not fully removed. These left behind registry entries can cause problems in installing a new version of Java. The following are the methods to cleanup registry entries:

Jdk-8u151-macosx-x64.dmg

• Program Install and Uninstall troubleshooter (Recommended Method)
• Manual Registry Edit

Program Install and Uninstall troubleshooter (Recommended Method)

Run the Program Install and Uninstall troubleshooter to repair the corrupted registry keys that prevent programs from being completely uninstalled, or blocks new installations and updates.

Manually edit the registry (Use this only if the Fix It utility does not work)

Incorrectly editing your registry may severely damage your system. You should back up any valued data from your computer before making changes to the registry.

Use the File->Export functionality of the registry editor to save the registry key before deleting. In case you deleted the wrong registry key, you can restore the registry from your saved backup file, by using the File->Import functionality.
