Download and Install Java JDK

In this post, you will learn the steps involved in downloading and installing the JDK( Java Development Kit). The easiest way to install JDK is to extract the zip file and set the JAVA_HOME and Classpath environment variables. However, we will use the JDK installer to examine the installation steps.

We need to download and obtain a copy of the JDK installer. The latest JDK only supports 64-bit installers, and almost any computer now has a 64-bit processor. It is recommended that you install the latest 64-bit version of JDK.

File Formats

JDK Installer file format example:

jdk-<version>_windows-x64_bin.exe

JDK zip file format example:

jdk-<version>_windows-x64_bin.zip

JDK 16 Install

Browse the official website to download JDK.

Download the JDK installer on to the computer.

Run the JDK Installer

Open Windows Explorer and navigate to where you saved the JDK installer.
Double-click on the file name to launch the install wizard.

JDK UAC Elevation Prompt

You must have administrative permissions to install the JDK on Microsoft Windows. To do so, click Yes on the UAC( User Access Control ) elevation dialog.

When the JDK installer starts, the welcome screen will appear. Click on the Next > button.

JDK Install Screen

The JDK installer asks for the Destination folder. On this screen, we can change the JDK installation folder. In most cases, it is best to use the default destination folder. Once done, click on the Next button.

Install Java JDK

When the JDK installation has been completed successfully, it should display a Complete screen. Click Close to exit the installer.

Update the PATH Environment Variable

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

It is useful to set the PATH variable permanently so it will persist after rebooting.

Add the full path of the JDK directory to the PATH variable to set the PATH variable permanently. Set the PATH variable as follows on Microsoft Windows:

Click Start, then Control Panel, then System.
Click Advanced, then Environment Variables.
Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.
