Java is a powerful programming language that is widely used for developing various types of software applications. It was created by Sun Microsystems, which is now owned by Oracle Corporation. One of the key features of Java is its platform independence, which means that Java programs can run on any device or operating system that has a Java Virtual Machine (JVM) installed.
Java is known for its simplicity and readability, making it easier for programmers to write and maintain code. It follows the principle of “write once, run anywhere,” allowing developers to write code once and deploy it on multiple platforms without making any changes.
Moreover, Java has a vast ecosystem of libraries, frameworks, and tools that support various development needs, including enterprise applications, web development, mobile app development, and more. This rich ecosystem, combined with its portability and security, has contributed to Java’s widespread adoption in the software industry.
In this guide, we will be guiding you on how you can install Java Windows.
Follow the below step-by-step guide on how to run Java on Windows operating system.
Step 1: Download Java Development Kit (JDK)
To download Java for Windows, visit the official Oracle website to download the Java Development Kit (JDK). The JDK contains everything needed to compile and run Java programs.
Ensure that you download the appropriate version of JDK for your Windows system. Choose between the latest stable version or a specific version depending on your requirements.
Step 2: Run the Installer
Once the JDK installer is downloaded, locate the file and double-click to run it.
You may encounter a security prompt asking for permission to run the installer. Confirm and proceed.
Step 3: Accept License AgreementDuring the installation process, you’ll be presented with the Oracle Binary Code License Agreement. Read through it carefully and if you agree to the terms, accept the agreement to proceed.
Step 4: Choose Installation Location
Next, you’ll be prompted to choose the installation location for the JDK. By default, it will be installed in the Program Files directory on your system drive (usually C:\). You can change this location if necessary.

Step 5: Install JDK
Once you’ve chosen the installation location, proceed with the installation by clicking the “Install” or “Next” button. The installer will now copy the necessary files and configure the JDK on your system. This process may take a few minutes to complete.
Step 6: Verify InstallationTo verify that Java has been installed correctly, open Command Prompt and type java -version. This command will display the installed Java version. Similarly, you can type javac -version to verify the installed Java compiler.
java -version
javac -version
Step 7: Set Environment Variables (Optional)After the installation is complete, you may need to set up the JAVA_HOME environment variable to point to the JDK installation directory.
To set the JAVA_HOME variable, right-click on “This PC” or “My Computer” and select “Properties”. Then, click on “Advanced system settings” and navigate to the “Environment Variables” section.

Under the “System Variables” section, click “New” and add a variable named JAVA_HOME with the path to your JDK installation directory (e.g., C:\Program Files\Java\jdk-21).
Java Tools: JDK and JRE are tools for Java programming language. If you only need to execute existing Java programs, you just need the JRE. While JDK is used for developing Java applications.
Cross-Platform Compatibility: Java can run on multiple platforms, including Windows. This means that Java applications developed on Windows can seamlessly run on other operating systems like Linux or macOS without needing any modifications.
Enterprise Applications: Java is widely used in developing enterprise-level applications on the Windows platform. Many organizations rely on Java for developing mission-critical systems such as banking applications, CRM and ERP structures.
Rich Ecosystem: The Java ecosystem on Windows offers a vast array of libraries, frameworks, and tools that facilitate development. IDEs (Integrated Development Environments) like IntelliJ IDEA, Eclipse, and NetBeans provide comprehensive support for Java development on the Windows platform.
GUI Development: Java’s Swing and JavaFX libraries enable developers to create cross-platform graphical user interfaces (GUIs) for Windows applications. These libraries offer a wide range of UI components and allow developers to design visually appealing and interactive interfaces.
Web Development: Java’s presence on the Windows platform extends to web development through technologies like JavaServer Pages (JSP), Servlets, and frameworks like Spring MVC. These technologies empower developers to build dynamic and scalable web applications that run on Windows servers.
Mobile Development: While Android development primarily utilizes Java, developers on the Windows platform can leverage tools like Android Studio to build native Android applications using Java.
Database Connectivity: Java provides robust support for database connectivity. This support enables Java applications to interact with various databases, including MySQL, Oracle, and Microsoft SQL Server, allowing seamless integration with data storage and retrieval mechanisms.
Java is a versatile programming language with platform independence, simplicity, and a rich ecosystem. Its widespread adoption across various sectors, including enterprise, web, mobile, and GUI development.
This guide provides a detailed and step-by-step process to install Java on Windows. Using Java on Windows allows developers to create robust, scalable, and secure software solutions catering to diverse needs effectively
