Is it legal to use two if-commands between the same parenthesis?

}

Answer 1

Here comes a little more code...
I hope it can help you guys.
The problem is that the program never reaches "access granted", even though both if(checkpassword(user, password) and if(onetime) separatly reaches "access granted".
public void actionPerformed(ActionEvent e)
     if(e.getSource() == klarknapp)
          user = name.getText();
          name.selectAll();
          password = date.getText();
          date.selectAll();
          if((checkpassword(user, password)) && (onetime))
          System.out.println("Access granted");
     }
