From what I can understand you are on the right track. Given you read the data you have provided as one single string, you can use the split(",") method on it and store the result of that into an array of strings.

I would probably split on ','.
If you were worried about efficiency, it would be a good idea to create a java.util.regex.Pattern object with (for e.g.)
Pattern pat = Pattern.compile(",");
then whenever you wanted to use it, using:
pat.split(theString);
