The public JRE installed with the JDK is not registered. When you are finished with the installation, you can delete the downloaded file to recover disk space. If you previously chose to hide some of the security prompts for applets and Java Web Start applications, the installer provides an option for restoring the prompts. The installer notifies you if Java content is disabled in web browsers, and provides instructions for enabling it. Follow the instructions the installer provides. If you saved the JRE installer to your computer, run the installer by double-clicking it. 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.You must have administrative permissions in order to install the JRE. Click OK to close the environment variables panel. Note that in case a 'PATH' variable is already present you can add %JAVA_HOME%\bin at the end of the variable value. Click OK to to save.Ĭlick on the New button and enter PATH as variable name and %JAVA_HOME%\bin as variable value. In this tutorial the installation directory is 'C:\Program Files\Java\jdk-10.0.1'. For this example click on Edit environment variables for your account and following panel should appear.Ĭlick on the New button and enter JAVA_HOME as variable name and the as variable value. Click on the Windows Start button and enter env without quotes as shown below.Įnvironment variables can be set at account level or at system level. When using Windows the above parameters can be configured on the Environment Variables panel. 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. ![]() 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. as shown below.Ĭlick Next and then Close to finish installing Java. Select the Public JRE dropdown and click on This feature will not be available. We will not install the public JRE as the JDK Development tools include a private JRE that can run developed code. From now on we will refer to this directory as. In this example the default install location of 'C:\Program Files\Java\jdk-10.0.1\' was kept. Once the download is complete, locate the jdk-10.0.1_windows-圆4_bin.exe file and double-click to run the installer.Ĭlick Next and on the following screen optionally change the installation location by clicking on the Change. Sign in using your Oracle account (or create a new one) and the download should start. ![]() ![]() In this example, we will use the Windows 64 bit version. Here is the direct link to download the jdk 10.0.1 installer for Windows 64 bit.Īccept the License Agreement and pick the correct download for your operating system. Click on the Download button right below JDK. The JDK package also comes with a Java runtime environment (JRE) that is needed to run compiled Java code.Īs we are installing the latest Java version, you can find it at the top of the Oracle Java download page. In order to be able to compile Java code, we need the Java Development Kit (JDK) package that comes with a Java compiler. There are a number of different Java packages available, for this tutorial we will be installing Java Standard Edition (SE) on Windows. Java can be obtained from the Oracle Java download page. Check following guides if you are looking to download and install JDK 1.5, JDK 1.6, JDK 1.7, JDK 1.8 or JDK 1.9. ![]()
