How do I move to absolute or relative row?

In this example we are showing you how to use result set absolute() and relative() method to jump from one result set row to the other. When you pass a positive number as the parameter you’ll move from the first record to the last. But if you pass a negative number as parameter you’ll move from the last record backward.

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 MoveAbsoluteOrRelativeExample {
    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 rs = statement.executeQuery(sql);

            // Move to the second row
            rs.absolute(2);
            System.out.println("You are now in: " + rs.getRow());

            // Move 2 records forward from the current position 
            // (fourth row)
            rs.relative(2);
            System.out.println("You are now in: " + rs.getRow());

            // Move to the last row in the result set
            rs.absolute(-1);
            System.out.println("You are now in: " + rs.getRow());

            // Move 3 records backward from the current position 
            // (second row)
            rs.relative(-3);
            System.out.println("You are now in: " + rs.getRow());
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

The code output the following result:

You are now in: 2
You are now in: 4
You are now in: 5
You are now in: 2
