Package Import Import Import Import

This Java code defines a 'conexion' class that is used to connect to a MySQL database called 'dbcalibracion' located at 127.0.0.1. The class stores the database name, URL, username and password as properties. It contains a 'conectar()' method that returns a Connection object by loading the MySQL driver, and calling getConnection on the DriverManager using the URL, username and password properties. Any errors connecting are caught and displayed in a JOptionPane dialog box.
