Write an application that implements a simple text editor. Use a text field and a button to get the file. Read the entire file as characters and display it in a TextArea. The user will then be able to make changes in the text area. Use a Save button to get the contents of the text area and write that over the text in the original file.
Hint: Read each line from the file and then display the line in the text area using a method, maybe called appendText(aString). A method, maybe called getText, will return all of the text area in a string that then can be written to the file.
