I have to store them in an ArrayList of object and I have to use non-word characters as a delimiter to split these data should I make a method and inside this method a 1-dimensional array and then use split() method?

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 think that splitting on 'non-word characters' would not be a good idea, as for example you would not want 4.5 to be split into 4 and 5.
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);
