Installing the JDK (Java Development Kit) on Windows 10 is vital for anyone looking to develop Java applications. Here’s a quick guide to help you through the process: download the JDK installer from Oracle’s website, run the installer, follow the prompts to complete the installation, and then set the Java environment variables.
How to Install JDK on Windows 10
In this section, we’ll walk you through the steps to install the JDK on your Windows 10 machine. Following these steps will ensure you have a working Java development environment.
Step 1: Download JDK Installer
Visit the Oracle website and download the JDK installer for Windows.
Head over to the official Oracle website. Look for the latest version of the JDK, and make sure to choose the Windows version. Click on the download link to save the installer file to your computer.
Step 2: Run the Installer
Double-click the downloaded installer file to begin the installation process.
Locate the downloaded JDK installer file on your computer. By default, this should be in your "Downloads" folder. Double-click the file to open the installer. This will launch the installation wizard that guides you through the setup process.
Step 3: Follow the Prompts
Accept the license agreement and follow the prompts to install JDK.
During the installation process, the wizard will prompt you to accept the license agreement. Be sure to read through it and click "Accept" to proceed. Follow the additional prompts to complete the installation. Keep the default settings unless you have a specific reason to change them.
Step 4: Set Java Environment Variables
Navigate to the System Properties and set the JAVA_HOME and PATH environment variables.
Go to the Control Panel, then "System and Security," followed by "System." Click on "Advanced system settings" and then "Environment Variables." Under System Variables, click "New" to add the JAVA_HOME variable and set its value to the JDK installation directory. Also, update the PATH variable by adding the JDK bin directory.
Step 5: Verify the Installation
Open Command Prompt and type java -version to verify the installation.
Open a Command Prompt window by typing "cmd" in the Windows search bar and hitting Enter. Once the Command Prompt is open, type java -version and press Enter. You should see details about the JDK version you installed, confirming the installation was successful.
After completing these steps, your computer will be ready to develop and run Java applications. You have successfully installed the JDK and set up the necessary environment variables.
