Write a JavaFX 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 original file. Technical Details: Read each line from the file and then use the method append( aString) to display the line in the text area. The method getText will return all of the text in the text area in a string that then can be written to the file.
Surprisingly, using just the built-in text area component of Java a simple editor can be created. The text editing is done via the operating system on the text in the component. What is left for us to do is to read and write the file, which is accomplished with a pair of methods.
See the code in SimpleEditor.java.
