I created a signup program to get the user details and I stored temporarily, but I need to store it under text file in a notepad for the further programming purpose. But I don't know how to store the user details in a notepad as a txt file. I want to store the received user details in a notepad.

try {
FileWriter writer = new FileWriter(file);
writer.write(text);
writer.close;
catch (IOException e) {
e.printStackTrace();
}
this should write text to a file, given that the file inputted is a txt file

Is it possible to create a text file and then on the same run or runtime of the code also read and write in these files? Java

I was working on a Uni project for the end of the semester. The program is a simple bank system. My issue is that when the program first launches it creates a "Log" folder. Then when an account object is created using a Constructor a new txt file is created in the folder with the name of the account holder. Up until here I have managed to do it.
The issue is that when closing the program via the option menu but before closing the program, all the details from all the created objects (which are stored in a array) are written in their respective files following the order they are stored in the object array but on the first run the files are created but nothing is written in them.
Then on the 2nd run if I close the program again the details are written correctly. Can I have some suggestions please I could not find anything regarding this online?

I have updated the post showing how I fixed it and providing all my classes. Please do not mind the messy code as I am first trying it out with a switch and then will ditch that when the time comes and use GUI as soon as I learn how to use it. Also I know that the classes can be organized better but BankAccount and eBanking are 2 salvaged classes I used on a different exercise.

I think I have found a solution. I just remembered that when using FileWriter if a file does not exist it creates one automatically. So i have cancelled the method which creates a file whenever a new object is created and now whenever the program is closed the files are created if needed or overwritten if they already exist.
I have provided all the current code on my program and the fix I implemented on FileManagment class

Turning a program - which writes to a file - into a GUI

my program works great and next, I want to turn it into a GUI. I have a menu:
System.out.println("Menu: ");
System.out.println("1) Enter Student Grade(s)");
System.out.println("2) View Student Grade(s)");
System.out.println("3) Delete Student Grade(s)");
System.out.println("4) Exit");
I'm not sure how to implement this into a GUI. I could maybe have 4 text fields: First name, Last name, unit and mark. I could have a button to delete, and a button to open the 'GradeEnter.txt' file perhaps. Again, I am not sure how I would implement this into a separate GUI class. Could anyone help or get me started? Thanks
