Java8 lambda: sort a stream in reverse order?

It's a type inference issue. You'll need to help the compiler out.

few things you could try:

.sorted(comparing(T::getDailyPercentageChange).reversed())

or

.sorted(comparing((T mps) -> mps.getDailyPercentageChange()).reversed())

Where T is the type of elements being compared.

Comparators have a reversed method to get the reverse ordering, so :

.sorted(comparing(mps -> mps.getDailyPercentageChange()).reversed())

should work.
