ELIZA was a program written in 1966 that parodied a psychotherapist session. The user typed sentences and the program used those words to compose a question. Create a simple applet based on this idea. The applet will use a label to hold the program’s question, a text field into which the user can type an answer, a button for the user to signal that the answer is complete, and a quit button. The initial text for the question label should read: “What would you like to talk about?” When the user presses a button, get the text from the text field. Now extract the words from the text one at a time and find the largest word of length 4 or more. Let’s call this largest word X for now. In response, create a question based on the length of the word. If the word is length 4, the new question is: “Te

Question

```
String text = “ one potato two potato “;
Scanner parser = new Scanner(text);
System.out.println(parser.next());
System.out.println(parser.next());
```
display one and potato on separate lines.

This programming project should be moved to Chapter 8 since event handling is not discussed at this point in the text, so processing button clicks hasn’t been covered.

This project looks at a tiny piece of computing history and can be used to introduce questions of artificial intelligence. The actual implementation of our application is pretty simple. Extending this applet to do a more complicated parsing of the input would be interesting. It would probably be a good idea as the action becomes more complicated move the parsing code out of setOnAction into its own dedicated method or methods.
