import java.sql.SQLException;
public class DatabaseConnection {
public static void main(String[] args) {
String url = "jdbc:mysql://localhost:3306/mydatabase";
String user = "username";
String password = "password";
try (Connection connection = DriverManager.getConnection(url, user, password)) {
System.out.println("Connected to the database!");
} catch (SQLException e) {
System.err.println("Error connecting to the database: " + e.getMessage());
}
}
}
