criei 2 classes uma de conexão e outra dao
como eu conseguiria fazer uma validação de login/senha com essas duas classes
conexão
```
package semeq;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;

public class ConnectionFactory {
private static final String DRIVER = "com.mysql.jdbc.Driver";
private static final String URL = "jdbc:mysql://localhost:3306/helpsemeq";
private static final String USER = "root";
private static final String PASS = "";
public static Connection getConnection(){
try {
Class.forName(DRIVER);
return DriverManager.getConnection(URL, USER, PASS);
} catch (ClassNotFoundException | SQLException ex) {
throw new RuntimeException("Erro na conexão: ",ex);
}
}
public static void closeConnection(Connection con){
try {
if(con != null){
con.close();
}
}catch (SQLException ex) {
Logger.getLogger(ConnectionFactory.class.getName()).log(Level.SEVERE, null, ex);
}
}
public static void closeConnection(Connection con, PreparedStatement stmt){
closeConnection(con);
try {
if(stmt != null){
stmt.close();
}
}catch (SQLException ex) {
Logger.getLogger(ConnectionFactory.class.getName()).log(Level.SEVERE, null, ex);
}
}
public static void closeConnection(Connection con, PreparedStatement stmt, ResultSet rs){
closeConnection(con, stmt);
try {
if(rs != null){
rs.close();
}
}catch (SQLException ex) {
Logger.getLogger(ConnectionFactory.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
classe do DAO
