5. Multiple versions

Understanding the connection between multiple Java versions and checking the correct version is crucial for successful Java usage. Many applications rely on specific Java versions to function properly. Having multiple versions installed can lead to conflicts and unpredictable behavior. Therefore, it’s essential to verify the version that your application or development environment requires.

To determine the required Java version, consult the application’s documentation or the Java Development Kit (JDK) documentation for development purposes. Once you know the necessary version, you can check the installed Java versions using the methods described in the “How to check Java plugin version” guide.

For instance, if you’re running a Java application that requires JRE 8, you need to ensure that JRE 8 is installed and set as the default Java version. Using an incorrect version, such as JRE 17, may result in compatibility issues or errors.

In summary, checking the correct Java version is vital to avoid conflicts and ensure compatibility with your intended application or development environment. Failing to do so can lead to unexpected behavior or hinder your development process.
