Use JavaFX to build a GUI program that implements the Caesar Cipher algorithm, the CaesarCipherFX project.
Your user interface must include the following:Professional layout; the precise design is up to you.
A drop-down to select the Key. The Key must be an integer in the range -3.. 3; zero is an acceptable Key value.
A TextField (TF1) in which the user enters the message to be translated.
A read-only TextField (TF2), where the translated message will be displayed.
A Translate button that causes the translation to take place, using the TF1 message for input, translating the message, and displaying the result in TF2.
A Copy Up button that causes the contents of TF2 to be copied to TF1, and then clearing TF2. This makes it easy to translate a message, copy the message, and “untranslate” the message.
A Clear button that clears the Key selection, TF1, and TF2.
If the Translate button is pressed when no Key has been selected, an appropriate alert should display, informing the user that a Key must be selected before a translation can take place.
You should use the translate() method that you built for Week 1’s assignment to perform the Caesar Cipher translation. (Note that translate both encodes (key > 0) and decodes key < 0)).
Take sufficient screen shots to demonstrate that your program meets all requirements.Include the execution output of your program to convince a reader that it functions properly—both encoding and decoding messages.
Test your program with both positive and negative Key values, and text strings containing both alphabetic and nonalphabetic characters.
One test must show the alert that results when a Key has not been selected.
Paste these screen shots into an MS Word document.
For your final test, you use must use a Key value of -2 and the message “Qpeg wrqp c vkog – c nqpi, nqpi vkog ciq . . .”
Create a .zip file containing your Caesar Cipher project.Before zipping your project, right-click the project and “clean” it. This greatly reduces the file size and speeds up the program’s performance.
Then close NetBeans.
Add the MS Word document with your screenshots to your .zip file.
Rename your .zip file, following this pattern: LastName_Week2.zip.
Assignment Instructions—Part 2 Designing GUI Screens
Complete these steps for this assignment, Part 2 Designing GUI Screens.
Select a visual design software or prototyping tools of your choice.
Design the seven user interface screens required for the CapestraApp project.Note that the Employee Information report already is implemented in the CapestraApp template application.
Place each screen on a separate page in an MS Word document, labeling each screen appropriately.
Add your MS Word design document to the .zip file you created in Part 1 of this assignment.
