How do I find the smallest BigDecimal field in a collection using a Java stream?

I want to use the Java stream to iterate over the list and find the lowest price for BigDecimal The following instructions do not work (because min() does not accept BigDecimal

class Product {
    public BigDecimal price;
}

List<Product> products;
products.stream().min((Product) p -> p.price);

Solution

Since BigDecimal is already comparable, it is very simple:

BigDecimal min = products
        .stream()
        .map(Product::getPrice)
        .min(Comparator.naturalOrder())
        .orElse(BigDecimal.ZERO);
