How to Install JDK in Windows 10
Installing the Java Development Kit (JDK) on Windows 10 is a straightforward process. First, you need to download the JDK from the official Oracle website. Then, follow the installation wizard to install it on your system. Finally, set up the environment variables to make the JDK accessible from the command line.
Step-by-Step Tutorial on How to Install JDK in Windows 10
Follow these steps to successfully install JDK on your Windows 10 machine:
Step 1: Download JDK
Begin by downloading the JDK from the official Oracle website.
Visit the Oracle website and navigate to the JDK download page. Select the appropriate version for your operating system, which is Windows 10 in this case, and click the download link.
Step 2: Run the Installer
Once the download is complete, run the JDK installer file.
Double-click the downloaded file to start the installation process. A wizard will guide you through the installation steps. Make sure to follow the prompts and install the JDK in the default directory unless you have a specific preference.
Step 3: Set the JAVA_HOME Environment Variable
After installation, set the JAVA_HOME environment variable.
Right-click on ‘This PC’ or ‘My Computer’ and select ‘Properties.’ Navigate to ‘Advanced system settings’ and click on the ‘Environment Variables’ button. Under ‘System variables’, click ‘New’ and enter ‘JAVA_HOME’ as the variable name and the path to your JDK installation as the variable value.
Step 4: Update the Path Variable
Next, update the Path environment variable to include the JDK bin directory.
In the Environment Variables window, find the ‘Path’ variable under ‘System variables’ and select ‘Edit.’ Add the path to the JDK’s bin directory (e.g., C:Program FilesJavajdk-bin) and click ‘OK.’
Step 5: Verify Installation
Finally, verify that the JDK is installed correctly.
Open a Command Prompt window and type ‘java -version’ and ‘javac -version’. If the installation was successful, you should see the version information for both commands.
After completing these steps, your Windows 10 machine will be ready to compile and run Java programs using the installed JDK.
