    Default Banking System Problem HELP!

    Hello masters! This is my first post. I'm having problem with my Banking System program. I'm still finishing my program. The problem is in the part when you register. I used a code for a blank textfield that every time a user forgot to enter any information for the Username and Password a message box will pop up. But when you input characters in the username or password whether you leave the other textfield blank it still proceed to register. Can you help me guys??

    Your issue is here:
                                    if(passTxtRegistration.getPassword().length == 0 && userTxtReg.getText().trim().length() == 0)
    	 			{
    	 				JOptionPane.showMessageDialog(null, "Please fill out the informations!", "Message", JOptionPane.ERROR_MESSAGE);
    	 			}
     
    	 			else{
     
    	 			JOptionPane.showMessageDialog(null,"Successfully Registered!");
    	 			rehistro.setVisible(false);
    	 			log.setVisible(true);
    	 			}
    Look at the logic of the if statement. As it stands the program is doing exactly what you have told it to do.

    Honestly, I don't have much experience with RandomAccessFile but after a quick glance I don't see why you can't use it to take care of the username and password. Only issue I can think of is that the password would still be plain text, but I suppose there are ways of fixing that problem up.
