You can use an array of characters. The char type is intended to represent characters in Java.

String csv = "167, 27, 32, 195";
String[] numbers = csv.split(", ");
char[] chars = new char[numbers.length];
for (int i = 0; i < numbers.length; i++)
    chars[i] = (char)Integer.parseInt(numbers[i]);

This method assumes that the numbers in the CSV file are Unicode code points of the characters.
