Which method is used to retrieve data from a ResultSet in JDBC?

The ResultSet interface in JDBC provides various methods for retrieving data from the current row of a result set. Methods like getString(), getInt(), and getDate() are used to retrieve data of different types, depending on the column’s data type in the database. For example, getString() retrieves a string value, getInt() retrieves an integer, and getDate() retrieves a date value.

These methods are essential for accessing the data returned by a SQL SELECT query. They allow developers to extract and use the data within their Java application, providing the flexibility to handle various data types in a consistent manner. The correct use of these methods ensures that the data is retrieved accurately and efficiently.

Understanding how to use these ResultSet methods is crucial for any Java developer working with databases. Proper handling of data retrieval methods is key to building applications that interact with databases reliably and effectively.
