QUESTION
So I am trying to convert a String array into a character array and I keep running into this error: Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 16 . I even tried to increase my array size but that keeps happening.
The string that is in the file which is stored in the array is exactly 16 characters long. So that maybe the error?
