Avoid NoSuchElementException with Stream

Question

I have the following Stream:

Stream stream = stream();

T result = stream.filter(t -> {
    double x = getX(t);
    double y = getY(         


        

Answer 1

You can use Optional.orElse, it's much simpler than checking isPresent:

T result = stream.filter(t -> {
    double x = getX(t);
    double y = getY(t);
    return (x == tx && y == ty);
}).findFirst().orElse(null);

return result;
