You haven't provided the EncryptString Class, Any way I have
written the instruction in comment where you have to call the
encrypt and decrypt method from that class.
You will get the output as per the string returned from the
EncryptString class when you call the corresponding method to get
the string. Please refer th instructions in bold strings
OUTPUT:

The JavaFX framework provides more than one way to handle events. For event handlers, we could use inner classes, anonymous inner classes, or the new Java 8 feature of lambda expressions. In this discussion, you will explore these different ways of writing event handles in JavaFX. To prepare for this discussion, you must unzip the attached NetBeans project zip file (U4D1_HandleEvents.zip) and load it into your NetBeans IDE. The project uses an inner class to handle the click event on...

For this question you will need to complete the methods to create a JavaFX GUI application that implements two String analysis algorithms. Each algorithm is activated when its associated button is pressed. They both take their input from the text typed by the user in a TextField and they both display their output via a Text component at the bottom of the GUI, which is initialized to “Choose a string methods as indicated in the partially completed class shown after...
