BJP3 Self-Check 5.12: printLetters

Language/Type: Java errors fencepost String
Author: Leslie Ferguson (on 2013/04/01)

Consider the flawed method printLetters that follows, which accepts a string as its parameter and attempts to print the letters of the string, separated by dashes. For example, the call of printLetters("Rabbit") should print R-a-b-b-i-t. The initial code shown is incorrect. Correct it to produce the desired behavior. (Your method should print nothing if the empty string ("") is passed.)
