Updating The Environment Variables In Windows 10
Brief: Updating the environment variables in Windows 10 is an essential step to ensure that the Java Runtime Environment (JRE) operates correctly. By properly configuring the environment variables, you allow Windows to locate and use the correct version of Java for running Java-based applications and programs.
To update the environment variables, follow these steps:
1. Open the Control Panel by searching for it in the Windows search bar and selecting the “System” option.
2. Click on the “Advanced system settings” link on the left-hand side of the System window.
3. In the System Properties window, navigate to the “Advanced” tab and click on the “Environment Variables” button.
4. In the Environment Variables window, find the “Path” variable under the “System variables” section and click on the “Edit” button.
5. Add the path to the folder where the new version of Java is installed. For example, if you installed Java in the default location, the path would be “C:Program FilesJavajre1.X.Xbin” (replace “X.X” with the specific version number).
6. Click “OK” in all open windows to save and apply the changes.
Updating the environment variables ensures that Windows recognizes the new Java version and uses it instead of any older versions, allowing you to take full advantage of the latest Java features and improvements.
Verifying The Change In Java Runtime Environment
After successfully installing the new version of Java Runtime Environment (JRE) on your Windows 10 computer, it’s important to verify that the change has been implemented correctly. This step is crucial to ensure that your system is using the desired version of Java and that any applications relying on it will function properly.
To verify the change in JRE, follow these steps:
1. Open the Command Prompt by pressing the Windows key + R, then typing “cmd” and pressing Enter.
2. In the Command Prompt window, type “java -version” and press Enter. This will display the version of Java currently being used by your system.
3. If the displayed version matches the new JRE version you installed, congratulations! The change has been successfully verified.
4. If the displayed version does not match the new JRE version, there might be an issue with the installation or environment variables. Double-check the steps mentioned in the previous sections to ensure everything was done correctly.
By following this simple verification process, you can confirm that the Java Runtime Environment has been changed to the desired version on your Windows 10 computer.
