Hello Mark G. Ghrayeb

How familiar are you with JavaFX? Did you already tried some basic examples like a window with button?

If not, at first you should learn how javafx works. There are many youtube tutorials and you can also look at udemy.

TextArea has a clear() method.

clear.setOnAction(e -> {

ta.clear();
});

And for reading the text file I would write an extra method. Your code will be messy if you put everything into start()

When you open the application you need to read the file? Without an extra button?
In that case you can put readTextFile() into show()

And in your class you write a method readTextFile(){

}

And if I see it right you can use the file reading part from your other class. But you need to replace the print statements in case of errors with alerts.

Looks not so bad I would say. I just need a bit more informations.

The TextArea should show the content of your textfile, right?

And clicking on clear button clears the TextArea?
