Hi. I have trouble with my java code and this is the third time I ask the same question AS THE PREVIOUS "EXPERTS" haven't done what I asked them to do correctly I need my classes Person, PhoneBook, and GUI to work so I when press save button it should state the amount of saved "people" like "Saved 50 people to the file", currently I get "Saved 0 people to the file". I can't figure out how to proceed with the following task step and there is something wrong with my savebutton. It's either the save method in class PhoneBook or how savebutton is wired in class GUI to the method save, could also be in class PhoneBook in method load, method addPerson and method save. but either way, I need help with updating my java code for class GUI and any other methods that might need to be updated from my other two classes, so it does what is described on the Task in the picture below. Don't give me any explanation or suggestion on what I should do. as I clearly tried it and hit a wall on what to do here. I just want a detailed explanation of what was wrong with my code and how to do the rest of the tasks below with an updated code for class GUI and any other that might need it, so I can continue with this code myself.

The code is simple I have one class Person, PhoneBook, GUI, and a txt file called PhoneList. You write in the text field PhoneList.txt and then press Load button, it should say "Phone book loaded" and enables all button except for next, then you press Save button, then it says "provide a new name for file", you can write anything you like for example oooga.txt and it then after you wrote oooga.txt and pressed save should make the oooga.txt file and save the data from loaded Phonebook (PhoneList.txt) to the new ooog.txt file and state how many saved people it saved over to the new file. And here's where the trouble for my code is so far. If you run my current code it says "Saved 0 people to the file", I need it to say something like in the picture below "Saved 50 people to the file", so the user knows it has copied over the full phone list to the new file.

Below are 2 pictures, one for the task, and one for the class Person, and at the very bottom of this question post is two texts where you can copy and paste the code directly for the class PhoneBook and class GUI, as well as a picture of PhoneList.txt, so you don't have to rewrite them and know what PhoneList look like. You are allowed to change anything you like except for the methods name in any class or add new methods and change their type and parameters within the class Person and class PhoneBook.

[The PhoneList.txt]

Update GUI such that pressing either the active load button or 'return' in the search field extracts the string from the search field, clears the search field and calls with the extracted string the lood(arg) method of PhoneBook. If a file with the name arg can not be opened, then the the text "Try again" should be written to the name field. Type in the name of the existing file ("PhoneList.txt") into the search field and press 'return' 2 or the load button. The content of the file is loaded into the phone book and the string "Phone book loaded" should be written to the name field. All buttons except the next button should be unlocked and the GUI should book like Update GUI such that pressing the "Save phonebook" button reads the text string in the search field and clears the search field afterwards. If the text string is empty, then the text "Provide a file name" should be written to the name field. If the text string is not empty, call with it the save method of Phonebook and write its return value to the name field. Do not write the phone book to "PhoneList.txt", because you need this file and you may mess it up if your code is not working correctly.
