Não consigo DE JEITO NENHUM conectar no mysql

O código é:

public BancoDados() throws ClassNotFoundException, SQLException{

try {

Class.forName(“com.mysql.jdbc.Driver”);

// conexao = DriverManager.getConnection(“jdbc:mysql://10.10.40.17/cadastro”, “root”, “123”);

conexao = DriverManager.getConnection(“jdbc:mysql://localhost/revistas”, “root”, “123”);

} catch (Exception e) {

JOptionPane.showMessageDialog(null, e.getMessage(), “Erro abertura banco”, JOptionPane.ERROR_MESSAGE);

}

}
