(EASY) Given an input String and a char key, return the String after a key-character Caesar cipher where all the input letters are shifted up key letters ('A'==1, 'B'==2 etc.). This is also sometimes called a Vignere cipher. Precondition: the input String will have only capital letters in it, the input key will be a capital letter too.


apcsaEncryptCaesarStringKey("ABC", "A") → "BCD"
apcsaEncryptCaesarStringKey("HI", "B") → "JK"
apcsaEncryptCaesarStringKey("ZZTOP", "C") → "CCWRS"

...Save, Compile, Run (ctrl-enter)

public String apcsaEncryptCaesarStringKey(String str, char key) { }
