How can I convert this:
Map<String, Integer> itemsBought
So that I can add it on the ArrayList as Follows:
public void add(String prd, int qty){
orderList.add(new Order(prd, qty));
}
Are there other solutions beside this:
hashMap.keySet().toArray();
hashMap.values().toArray();
Thank you in advance.
for (Entry<String, Integer> entry : itemsBought.entrySet()) {
orderList.add(new Order(entry.getKey(), entry.getValue()));
}
for (String product : itemsBought.keySet()) {
int quantity = itemsBought.get(product);
orderList.add(new Order(product, quantity));
}
I prefer more readability (not much though)
