ResultSet&Statement Interfaces

The ResultSet and Statement interfaces are essential components in Java’s database connectivity framework, specifically JDBC (Java Database Connectivity). The Statement interface allows developers to execute SQL queries against a database, facilitating the retrieval and manipulation of data. Once a query is executed, the ResultSet interface provides a structured way to access the data returned by the database. It allows for iteration over the rows of data, enabling developers to extract and process results efficiently. Together, these interfaces form a crucial part of Java’s ability to interact with relational databases, ensuring smooth data operations in applications.
