PROBLEM: Stocks4U Portfolio Management System The portfolio management system you developed for Stocks4U needs the ability to save and restore a user's data from a text file. FUNCTIONAL REQUIREMENTS You can code the GUI by hand or use NetBeans GUI Builder Interface. You will enhance Week 4 GUI to include a File menu with menu items: open, save, exit; and a label to display total portfolio value. . Modify the toString of Stock class to display as "Company: qty shares" (i.e., "Apple: 10 shares") StocklQ class Create a StockIQ class that is used to read from and write to a text file using an ArrayList, Make sure to use a delimiter between the fields; it does not have to be the # character. Example format of the file is: Apple# 100#55.0#80.0 Intel# 50#75.0# 70.0 This class should have two methods. getData-reads data from file, returns data in array list of stock objects saveData-writes data from an array list to the file in proper format The file name will be an instance variable that you can set with a parameterized constructor, or with a separate method. Note that you will need to add an ArrayList to your GUI class to manage the data to/from the file. It will act as a parallel array to your DefaultlistModel. Any time you add a stock, you must add it in BOTH e a stock vou ust re nlaces Any time vou rema
