ResultSet&Statement Interfaces - Learn Data Science with Travis

ResultSet-and-Statement-Interfaces

The ResultSet and Statement interfaces are essential components of Java’s JDBC (Java Database Connectivity) API, which facilitates interaction with databases. The Statement interface is used to execute SQL queries against a database, allowing developers to send commands and retrieve results. It provides methods for executing various types of SQL statements, such as queries and updates. On the other hand, the ResultSet interface represents the result set of a query, allowing developers to navigate through the data returned by the database. Together, these interfaces enable efficient data manipulation and retrieval in Java applications, making them crucial for database-driven development.
