What can Java modules do for site development in Liferay?

Java modules in Liferay play a significant role in site development, particularly in generating new sites with a specific theme. They allow developers to encapsulate business logic and functionality, promoting reusability and ease of management across different parts of a site. By using Java modules, developers can create custom themes that not only modify the appearance of a site but also include features and functionalities tailored to that particular site's needs.

Option about solely managing content delivery does not accurately reflect the broader capabilities of Java modules, as they serve a wider purpose in application development. The choice about ensuring themes are installed correctly implies a passive role rather than the active function that Java modules provide in creating and managing themes. Lastly, while enhancing analytics is essential for understanding user traffic, it does not directly relate to the primary function of Java modules in site development, which is more about the operational and aesthetic aspects of site creation and management.
