How do I check if cursor is in the last row?

On the previous example we check for the beginning of the result set. Now using the isAfterLast() method we can check the opposite whether the pointer is at the end of the result set.

package org.kodejava.example.jdbc;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class ScrollableIsAfterLastExample {
    private static final String URL = "jdbc:mysql://localhost/kodejava";
    private static final String USERNAME = "root";
    private static final String PASSWORD = "";

    public static void main(String[] args) {
        try (Connection connection =
                 DriverManager.getConnection(URL, USERNAME, PASSWORD)) {

            Statement statement = connection.createStatement(
                ResultSet.TYPE_SCROLL_INSENSITIVE,
                ResultSet.CONCUR_READ_ONLY);

            String sql = "SELECT code, name, price FROM products";
            ResultSet resultSet = statement.executeQuery(sql);

            while (resultSet.next()) {
                // Read all ResultSet data
            }

            // Using the isAfterLast() method we can check if we are
            // at the end of the result set.
            if (resultSet.isAfterLast()) {
                System.out.println("You are at the end of the " +
                    "result set.");
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
