To install the JDK (Java Development Kit) on Windows 10 64-bit, follow these steps:

1. Download the JDK: Go to the official Oracle JDK download page (or the appropriate JDK provider) and download the latest version of the JDK for Windows 64-bit. You can find the JDK download page at: https://www.oracle.com/java/technologies/javase-downloads.html

2. Accept License Agreement: Before downloading, you’ll need to accept the Oracle Technology Network License Agreement.

3. Choose the appropriate version: Make sure to download the version labeled as “Windows x64.”

4. Run the installer: Once the download is complete, run the installer by double-clicking on the downloaded file.

5. Install the JDK: Follow the on-screen instructions of the installer. It will guide you through the installation process.

6. Set JAVA_HOME environment variable: After the installation is complete, you should set the JAVA_HOME environment variable to point to the JDK installation directory. This step is necessary for various Java applications and development tools to work correctly.

   • Right-click on “This PC” or “My Computer” and select “Properties.”
   • Click on “Advanced system settings” on the left side of the window.
   • In the System Properties window, click the “Environment Variables” button.
   • Under the “System variables” section, click “New.”
   • For the variable name, enter “JAVA_HOME.”
   • For the variable value, enter the path to the JDK installation directory. For example, it might look like: C:\Program Files\Java\jdk1.8.0_271 (the version number may vary depending on the JDK version you installed).
   • Click “OK” to close all the windows.

7. Update PATH variable (Optional): If you want to run Java commands from the Command Prompt without specifying the full path every time, you can add the JDK’s bin directory to the PATH environment variable.

   • Follow the same steps as above to access the “Environment Variables” window.
   • In the “System variables” section, locate the “Path” variable and click “Edit.”
   • Click “New” and enter the path to the JDK’s bin directory. For example, it might be: C:\Program Files\Java\jdk1.8.0_271\bin
   • Click “OK” to close all the windows.

8. Verify the installation: To verify that the JDK is installed correctly, open a Command Prompt and type the following command:

   Copy code

   java -version


   This should display the installed Java version, confirming that the installation was successful.
