Beginner’s Guide: How to Install Java on Windows


Java is a popular programming language used for developing desktop, web, and mobile applications. If you’re new to Java or programming in general, one of the first steps you’ll need to take is installing Java on your Windows computer. In this guide, we’ll walk you through the process of installing Java on Windows.

Downloading Java

The first step in installing Java on Windows is to download the Java Development Kit (JDK) from the official Oracle website. To do this, go to Oracle’s Java download page and click on the “Accept License Agreement” checkbox. Then, select the appropriate JDK for your Windows operating system (32-bit or 64-bit) and click on the download link.

Installing Java

Once the JDK download is complete, run the executable file to start the installation process. Follow the on-screen instructions to install Java on your Windows computer. During the installation, you may be prompted to set the installation directory and configure additional settings. Make sure to follow the prompts carefully to complete the installation successfully.

Configuring Java Environment Variables

After installing Java, you’ll need to set up the Java environment variables on your Windows system. This step is necessary to allow your computer to locate the Java compiler and runtime when running Java programs. To configure Java environment variables, right-click on “This PC” on your desktop and select “Properties.” Then, click on “Advanced System Settings” and go to the “Environment Variables” section. Under “System Variables,” click on “New” and add the following variables:

  • Variable name: JAVA_HOME
  • Variable value: C:\Program Files\Java\jdk-15 (replace “jdk-15” with your JDK version)
  • Variable name: PATH
  • Variable value: %JAVA_HOME%\bin

Verifying Java Installation

Once you’ve installed Java and configured the environment variables, you can verify the installation by opening a command prompt and typing “java -version” and “javac -version.” If Java is installed correctly, you should see the version number of Java and the Java compiler displayed in the command prompt.


Congratulations! You’ve successfully installed Java on your Windows computer. Now you’re ready to start programming in Java and developing your own applications.
