Hi. I have trouble with my java code. 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 it's wired in class GUI to the method save.

The code is simple I have one class Person, PhoneBook, GUI, and a txt file called PhoneList. You write in the textfield PhoneList.txt then press Load button, it hsould say Phone book loaded, then you press Save button, then it says provide a new for file, you can write anything you like for example oooga.txt and it should make the oooga.txt file and save from the PhoneList.txt to the ooog.txt file and state how many saved people it saved over to the new file. the rest of the information is in the task below. Below is 2 pictures, one for the task, one for the class Person, and two texts where you can copy paste the code directly for PhoneBook and GUI class, so you don't have to rewrite them. 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 Person and PhoneBook class.

[THis is the TASK]

[This is Class PhoneBook]

[The PhoneList.txt]

Update GUI such that pressing the "Save phonebook" button reads the text string in the search fleld 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. Update the GUI such that pressing the "Search" button reads the string in the search field and clears the search feld afterwards. The string ary that was read in is used to call the method search(arg) of PhoneBook. If the size of the dynamic array that is returned by the call is 0 , then the text "Provide a name" should be written to the name field and " " to the number feld. If the size of the dynamic array is 1 , then the full name of the returned person is written to the name field and the phone number to the number field. If the size of the returned array list exceeds 1 , then you enable the "Next name" button and set a person counter to 0 . The next figure shows the case where you searched for the surname "Walker", which exists twice. If you press the "Next name" button the value of the person counter should be increased by 1 and the GUI should display the next person in the dynamic array that was returned by the search. If you searched for Walker and preseed next once, your result should be that
