Answer 1

MY PROGRAM IS LIKE THIS:::::::::
STOCKNAME-----------
STOCKSYMBOL---------
STOCK PRICE--------
ENTER(BUTTON)
WHEN USER ENTERS HIS INPUT IN THE TEXT BOX AND PRESS ENTER, THEN THE TEXT PRESENT IN THE TEXTBOX SHOULD BE ENTERED INTO AN ARRAYLIST.
THIS IS A GUI PROGRAM......
WHEN WE CLOSE THE FRAME ,WE HAVE TO DISPLAY THE CONTENTS PRESENT IN THE ARRAYLIST
I HAVE CREATED THE PROGRAM LIKE THIS
CLASS STOCKENTRYPANEL EXTENDS JPANEL
//ADDING ALL THE COMPONETNS TO THE PANEL
CLASS STOCKENTRY FRAME EXTENDS JFRAME
//ADDING PANEL TO THE FRAME
//I NEED THE CODE HERE
WHEN WE CLOSE THE WINDOW THE ARRAYLIST DETAILS SHOULD BE PRINTED
