Question

for (String stock : allStocks) {

    Quote quote = getQuote(...);
    if (null == quoteLast) {
        continue;
    }

    Price price = quote.getPrice();
    if (null == price) {
        continue;
    }

}

I don’t necessarily need a line by line translation, but I’m looking for the “Scala way” to handle this type of problem.

Answer 1

You don’t need continue or breakable or anything like that in cases like this: Options and for comprehensions do the trick very nicely,

val stocksWithPrices =
  for {
    stock <- allStocks
    quote <- Option(getQuote(...))
    price <- Option(quote.getPrice())
  } yield (stock, quote, price);
