What does the ResultSet interface represent in JDBC?

The ResultSet interface in JDBC represents a table of data that is the result of executing a SQL query. It allows a Java application to retrieve and manipulate the data returned by a SELECT query. The ResultSet object contains rows of data, and the application can iterate through these rows using methods like next(), previous(), and absolute().

ResultSet provides various methods for retrieving data from the current row, such as getString(), getInt(), getDate(), and others. These methods allow developers to extract the data from the query results and use it within their application. The ResultSet is a fundamental component of JDBC, enabling interaction with the data stored in a database.

It is important to manage ResultSet objects properly, closing them when they are no longer needed to avoid memory leaks and ensure that database resources are released. Proper handling of ResultSet is crucial for building efficient and reliable database applications in Java.
