Help with empty textfields!!!

[Aash96]

Hi, i have login screen where the user i asked to enter his username and password. Now if these fields are 'blank' i want to output and error message, but it does not seem to work. Nothing happens!!

Here is my code: (NB. This is under my "Welcome" button...)

if(username.equals(""))
{
JOptionPane.showMessageDialog(null,"The Username cannot be left blank!");
}
else if(password.equals(""))
{
JOptionPane.showMessageDialog(null,"The Password cannot be left blank!");
}
else if((username.equals(""))&&(password.equals("")))
{
JOptionPane.showMessageDialog(null,"Please fill in the required fields!");
}

Have you tryed to compare your string with a null value instead of ""?

JOptionPane.showMessageDialog(null,"Please fill in the required fields!");
}
else if(password.getText().equals(""))

Good for you :)! I wrngly thought your username and password were of String type, not JTextField :)
