Installing Java on Windows

To install Java on Windows, follow these steps:

Step 1: Download the JDK

Go to the Oracle JDK download page, select the latest JDK version, and download the installer suitable for your system.

Once the file is downloaded, open it and follow the installation prompts. It’s usually fine to stick with the default options.

After installation, you’ll need to set up environment variables so your system can locate Java.

Open the Start Menu, search for environment variables, and click on Edit the system environment variables.
In the System Properties window, click the Environment Variables… button.
Under System variables section, find and select the Path variable, and click Edit….
In the Edit environment variable window, click New and enter the path to the JDK’s bin directory (e.g., C:\Program Files\Java\jdk-<version>\bin).
Click OK to close the window.
Back in the Environment Variables window, under System variables section, click New… to add a new variable.
Set the variable name to JAVA_HOME and the value to the JDK folder path (e.g., C:\Program Files\Java\jdk-<version>).
Click OK to close all open windows.

To ensure Java was installed successfully, open a Command Prompt window and run:

java -version

If you receive an error message, the installation might not have been completed correctly.
