Question

Case 0:   pri         


        

Answer 1

Apply the regex \d+\.?\d* as often as you can. The array of the results can be checked whether it contains 0, 1 or more values.

If there are 0, it is Case 0.

If there is one, it is Case 1. You can edd it with qunantity 1 to the articles.

If there are more, you can loop with something like

for(int i = 0; i < result.length / 2; i++) {
    articles.addArticle(Integer.parseInt(result[i]), Double.parseDouble(result[i+1]));
}
