Check if text field is empty 1

[stephenbruceburch]

I am having a problem and I believe this is where it lies. The program allows the user to identify an item by either its id or its location. I thought the easiest way to accomplish this was to just have both text fields in the panel and when the submit button was pressed check to see which was blank. that's where I'm having the problem (i think!)
I have tried these diffrent ways:
if (textField.getText() == null)
if (textField.getText() == " &quot
if (textField.getText() == "&quot

Any help would be appreciated

Typically, when you are validating user input in Java, you will want to check for both null and empty string values. To check String objects for equality, you must use the .equals() method (not the == operator). Thus, a check for an empty String value might look something like this:

if ( val == null || val.trim().equals( "" ) )
{
// handle empty String case
}
else
{
// handle non-empty String case
}

Hope this helps,
