problem in getting string from jTextField

hi...

i have a jTextField named pIdTextField on a JFrame along with a button named btnSave . i want that when pIdTextField is blank... then it should show a message Saving. i have tried in the code below...

private void btnSaveActionPerformed(java.awt.event.ActionEvent evt) { if (pIdTextField.getText() == null) { JOptionPane.showMessageDialog(null, "Saving."); } else JOptionPane.showMessageDialog(null, "Updating."); }

but when ever i click the btnSave button .... it always displays the message as Updating. . it never show the message as Saving.. i have tried "" instead null in the if condition .. but it doesn't show "Saving."
please help me... waiting for your kind response.

The empty String "" and null aren't the same thing.

Did you use == or the equals method to compare with "" ?

sir
i have tried == as---

if (pIdTextField.getText() == "") { JOptionPane.showMessageDialog(null, "Saving."); } else JOptionPane.showMessageDialog(null, "Updating."); }

but this too dos'nt solve my probleum that when the pIdTextField is left blank.... message Saving. should display.

Yeah, well don't do that. If you want to compare to see if two String objects contain the same data (even if that's no data) then use the equals() method to do the comparison.

thanks a lot Paul Clapham
as you suggested... i have tried the code below and it worked perfectly...

if(pIdTextField.gettext().equals("")){ // show Saving } else // Show Updating

thanks a lot again sir... :-)
