how to install JDBC and how to use it to connect to mysql?

Question

i am trying to install JDBC but i dont know how, when you only have the jar file, i copied it to my java ext folder but it keep giving me an error, can anyone show me how to complete install the driver and use it?

below is the codes that i used

import java.sql.*;
public class Test1
{
    public static void main (String[] args)
    {
        String url = "jdbc:mysql://localhost:3306/sabayafr_sabmah";
        String username = "root";
        String password = "ma";
        Connection connection = null;
        try {
            System.out.println("Connecting database...");
            connection = DriverManager.getConnection(url, username, password);
            System.out.println("Database connected!");
        } catch (SQLException e) {
            System.err.println("Cannot connect the database!");
            e.printStackTrace();
        } finally {
            System.out.println("Closing the connection.");
            if (connection != null) {
                try {
                    connection.close();
                } catch (SQLException ignore) {

                }
            }
        }
    }
}

You're trying to connect MySQL with the URL of a jTDS JDBC driver which is designed specifically for Microsoft SQL Server. This ain't ever going to work. Even not when you fix the current problem by placing the JAR file in classpath.

You really need the MySQL JDBC driver. Also see this answer for a short but complete tutorial
