What part of the ResultSet object does it refer to during initialization or when starting to work with data?

When initializing or starting work with a ResultSet object, the cursor is before the first row of the result. This means that to access data, you need to call the next() method, which moves the cursor to the first row and returns true if the row exists. Thus, data access occurs after calling next().

Example:

ResultSet rs = statement.executeQuery("SELECT * FROM users");
if (rs.next()) {
    String name = rs.getString("name");
    // process data
}
