Question

Here is the initiation code:

totalTextField.setText(
            itemsP         


        

Answer 1

Add a WindowListener to the frame. Then you can handle the windowActivated event and reset the text of the text field.

See How to Write Window Listeners.

Answer 2

Before setting the frame visible again, one should update the fields with the new values / states.
something like:

jTextField.setText("put your text here");  
jRadioButton.setSelected(!isSelected());  
.  
/* update all you need */
.  
jFrame.setVisible(true);

The frame will come up with the new values / states.
