How has ResultSet changed in recent Java versions?

The ResultSet interface in Java has undergone several enhancements in recent versions to improve functionality and performance when dealing with data retrieval from a database. Key updates include new methods for retrieving data types, improved support for streaming, and optimizations for handling large datasets.

One notable change is the introduction of methods such as getObject(String columnLabel, Class> type), which allows developers to retrieve a column value with a specific Java type. This adds flexibility when working with various data types and enhances type safety. Additionally, performance improvements have been made regarding the handling of large ResultSets through better memory management.

Another significant enhancement is the integration of the ResultSet.getFetchDirection() method, which indicates the direction of fetching rows in a ResultSet, giving developers better control over data retrieval strategies.

Overall, these changes make the ResultSet interface more effective for modern database applications, allowing for more robust error handling and greater adaptability to complex data structures.
