Answer
Closing a ResultSet releases database and JDBC resources.
Failing to close a ResultSet can lead to resource leaks, which might exhaust database connections and degrade performance. Always close ResultSet in a finally block or use try-with-resources to ensure it is closed even if an exception occurs. For instance, in an e-commerce application, not closing a ResultSet could prevent other users from querying the product database efficiently.
