The JAVA_HOME environment variable is not defined correctly, this environment variable is needed to run this program

This error message is typically seen when attempting to run a Java program or application, but the system is unable to locate the necessary Java installation.

To resolve this issue, you will need to set the JAVA_HOME variable to the correct path where your Java installation is located.

Here are the steps to set the JAVA_HOME environment variable on Windows:

1. Open the Start menu and search for "Environment Variables" or "Edit the system environment variables" and click on it.
2. In the System Properties window, click on the "Environment Variables" button.
3. Under "System Variables", scroll down and find the JAVA_HOME variable.
4. If it is not already set, click on the "New" button to create a new variable.
5. Set the variable name to "JAVA_HOME".
6. Set the variable value to the path where your Java installation is located. For example, "C:\Program Files\Java\jdk1.8.0_221".
7. Click "OK" to save the changes.

After setting the JAVA_HOME variable, try running your Java program again. It should now be able to locate the necessary Java installation and run the program successfully.
