JtextField returning empty!

[tamasu]

Hi,

I am trying to read text from a simple Jtextfield using the syntax

String StrRound = txtRoundName.getText();
if (StrRound.equals("")) ... etc

I am also using the method dispose() to close the window. Since when
the window is re launched the previous contents inserted in the
txtRoundName is displayed, I had to clear the fields using
txtRoundName.setText(""); in a separate method.

I found out that when enabling the setText(""), the condition if
(StrRound.equals("")) is returning that the string StrRound is empty
(actually the user keys in some data). Whilst, when I remove the
statement txtRoundName.setText("") everything works fine.

The window is instantiated through a separate class.

Could you highlight why this is occurring?

Thanks

Nothing wrong with that.

I don't think dispose() will do anything to the value entered into your
JTextField.

It's not really clear what you are doing.

Not without some code and preferably an SSCCE.

Well, one slight deviation from the Java coding conventions - variable names
are supposed to start with a lower-case letter conventionally.
