why we use a resultset to the type de retour

Hey,

If I am not missing anything, it sounds like you’re asking about why we use a ResultSet in Java as the return type when working with databases. Is this the case?

If so, a ResultSet is usually used to represent the results of a query executed on a database using JDBC. It allows you to iterate through the rows of the result and access the data from the database in a structured way. Think of it as a “view” of the data returned by the database query.

Here’s a quick example:

ResultSet rs = statement.executeQuery("SELECT * FROM users");
while (rs.next()) {
    System.out.println("User ID: " + rs.getInt("id"));
    System.out.println("Name: " + rs.getString("name"));
}

Using ResultSet lets you access the columns in each row of the returned data by their name or index.

If this isn’t quite what you meant, could you clarify? Are you working with JDBC, Hibernate, or another framework? Also, if you’re following a specific DigitalOcean tutorial, feel free to share the link or its name so we can better understand your context and provide a more targeted answer.
