A two-parameter constructor to initialize
key and code
A method public String decode ()
that will return a "decoded" message. The
message has been encoded in the following
manner: each integer in code is an index
pointing to a location in key. To decode
the message, simply look up each integer in
key and output the corresponding
character.
To test your method, create a new SecretCode
object in the Runner class with the following
inputs:
19
=
=
String key "six perfect quality black
jewels amazed the governor"
String code "35 10 10 33 9 24 3 17 41
8 3 20 51 16 38 44 47 32 33 10 19 38 35
28 49"
If your method is written correctly, it should return
a covert message. You must use a Scanner object
to parse the String (rather than split () and
Integer.parseInt ())! Scanner objects will
help on this and future labs.
