Question: Set up a class named MyCipher. The class will have private int data member named key. It also has the following methods:

• a constructor initializing key with 0

• a method named setKey(int k) that takes a positive integer and puts it into key

• a get method for key

• a method named encode(String s) that takes a text file and encodes it to a new cipher text file by adding the key value to each alphabet character in the plain text file For example, if the first line of plain text is "attack at dawn" and key is 5, it should be encoded as "fyyfhpefyeifas" because 'a' 5 = 'f', 't' 5 = 'y', 'c' 5 = 'h', 'k' 5 = 'p', ' ' 5 = 'e', 'd' 5 = 'i', 'w' 5 = 'a', and 'n' 5 = 's'. The String s accepted as a parameter for the encode method should be the path and filename of the .txt file you are wanting to encode. For example, to encode the file I gave you to test with, your argument passed to encode() might contain "c:\\java\\attack.txt"
