package model;
import java.sql.DriverManager;
import java.sql.Connection;

public class Conexao {
  public static void main(String[] argv) throws Exception {
    String driverName = "com.mysql.cj.jdbc.Driver";
    Class.forName(driverName);

    String serverName = "phpmyadmin";
    String mydatabase = "dbquality";
    String url = "jdbc:mysql://localhost:8080/" + serverName + "/" + mydatabase; 
                                                                    
    String username = "root";
    String password = "";
    Connection connection = DriverManager.getConnection(url, username, password);
    
 
  }
}

agora parou o erro, como sei que está conectado?

Muda para isso:

try {
	Connection connection = DriverManager.getConnection(url, username, password);
	System.out.println("Acessou");
	} catch (Exception e) {
		// TODO: handle exception
		System.out.println("Não Acessou");
	}
