Olá.
Fiz um código para puxar consultas de um banco de dados por JTable.
Só que quando vou rodar não acontece nada,não da nem saída de console.
Se alguém puder me ajudar.
Aí vai o código:
package TabelasB;
import java.sql.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.BorderLayout;
import java.util.*;
