2.1 Installing JRE (version 1.8 or above) Downloading & Installing the JRE Installer on Windows platform: OpKey Web supports Java 8 or above versions. JDK is a superset of JRE, and contains everything that is in JRE, plus tools such as the compilers and debuggers necessary. Server JRE (Java SE Runtime Environment) 8 Downloads. Thank you for downloading this package of the Java™ Platform, Standard Edition Runtime Environment (JRE™). The Server JRE is a runtime environment specifically targeted for deploying Java in server environments and it is available for 64-bit Linux, Solaris and Windows platforms.
Download Java Runtime Environment (JRE) for Windows to run Java applications on your Windows computer. Java Runtime Environment (JRE) has had 2 updates within the past 6 months. Download Java SE 8 Environment 8 1.8.11.12 for Mac. Fast downloads of the latest free software!
The following are the system requirements for installing the JDK and the JRE on macOS:
- Any Intel-based computer running macOS.
- Administrator privileges.You cannot install Java for a single user. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK and JRE on macOS.
- When you install the JDK, it also installs the JRE. However, the system will not replace the current JRE with a lower version.To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.
- When you install the JRE, you can install only one JRE on your system at a time. The system will not install a JRE that has an earlier version than the current version.To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.Note:Installing a JRE from Oracle will not update

This tutorial has everything you need to know about installing JDK 8 on Windows.
If you’re new to Java, I’ll show you how to setup the Java Development Kit.
And if you’re a Java pro? I’ll highlight the needed links that you can use to download the installer.
Bottom line:
If you want to get up and running with Java, you’ll love this tutorial.
Java is a computer programming language that is concurrent, class-based and object-oriented. Java applications compile to bytecode (class file) that can then run on a Java Virtual Machine (JVM).
James Gosling created Java at Sun Microsystems. It is currently owned by the Oracle Corporation.
Consult following posts if you are looking to download and install JDK 1.5, JDK 1.6, JDK 1.7, JDK 1.9 or JDK 1.10.
Java can be obtained from the Oracle Java download page. There are a number of different Java packages available, for this tutorial we will be installing Java Standard Edition (SE) on Windows.
In order to be able to compile Java code, we need the Java Development Kit (JDK) package that comes with a Java compiler. The JDK package also comes with a Java runtime environment (JRE) that is needed to run compiled Java code.
Scroll to the Java SE 8u171/ 8u172 section in the middle of the Oracle Java download page and click on the Download button right below JDK. Then look for the Java SE Development Kit 8u172 section.
Jvm 1.8 Download
Here is the direct link to download the jdk 8u172 installer for Windows 32 or 64 bit.
Accept the License Agreement and pick the correct download for your operating system. In this example, we will use the Windows 64 bit version.
Sign in using your Oracle account (or create a new one) and the download should start. Once the download is complete, locate the jdk-8u172-windows-x64.exe file and double-click to run the installer.
Click Next and on the following screen optionally change the installation location by clicking on the Change... button. In this example the default install location of 'C:Program FilesJavajdk1.8.0_172' was kept. From now on we will refer to this directory as: [java_install_dir].
We will not install the public JRE as the JDK Development tools include a private JRE that can run developed code. Select the Public JRE dropdown and click on This feature will not be available. as shown below.
Click Next and then Close to finish installing Java.
In order for Java applications to be able to run we need to setup a 'JAVA_HOME' environment variable that will point to the Java installation directory. In addition, if we want to run Java commands from a command prompt we need to setup the 'PATH' environment variable to contain the Java bin directory.
When using Windows the above parameters can be configured on the Environment Variables panel. Click on the Windows Start button and enter “env” without quotes as shown below.
Environment variables can be set at account level or at system level. For this example click on Edit environment variables for your account and following panel should appear.
Click on the New button and enter “JAVA_HOME” as variable name and the [java_install_dir] as variable value. In this tutorial the installation directory is 'C:Program FilesJavajdk1.8.0_172'. Click OK to to save.
Click on the New button and enter “PATH” as variable name and “%JAVA_HOME%bin” as variable value. Click OK to save.

Note that in case a 'PATH' variable is already present you can add “;%JAVA_HOME%bin” at the end of the variable value.
The result should be as shown below. Click OK to close the environment variables panel.
In order to test the above configuration, open a command prompt by clicking on the Windows Start button and typing “cmd” followed by pressing ENTER. A new command prompt should open in which the following command can be entered to verify the installed Java version:
The result should be as shown below.
This concludes the setting up and configuring JDK 1.8 on Windows.
