Q#1: Read pages 104 to 106 from the official book, and run in your laptop the corresponding program :

CaesarCipher. Generalize the test for a complete text.

Explain the changes that would have to be made to the program of code fragment 3.7 so that it could perform Caesar cipher for messages that are written in Arabic.

Java allows us to "subtract two characters from each other, with an integer result equal to their separation distance in the encoding, Given a variablec that is known to be an uppercase letter, the Java computation.)
