class fill table made in class DAO [closed]

I'm a little fussy and I would appreciate the help.

The project works, inserts users into the database, but I would like to make a jtable to display the data entered;

Here is the complete project (I'm having trouble posting here link

 SQL:

    create database projetojava; 
    use projetojava;
    CREATE TABLE usuario ( 
    id BIGINT(10) AUTO_INCREMENT, 
    nome VARCHAR(255), 
    cpf VARCHAR(255), 
    email VARCHAR(255),
    telefone VARCHAR(255), 
    PRIMARY KEY (id) );

    select * from usuario;

    Pacote DAO (Ao qual pretendo criar um método preencherTabela() )


        package dao;
