Java 8 – filtering with bipredicate

• Java

I have a stream of integers. I want to find two numbers whose sum is equal to the other number So I came up with the following solutions:

BiPredicate<Integer,Integer> p = (price1,price2) -> price1.intValue() + price2.intValue() == moneyQty;
flavoursPrices.filter(p);

However, the filtering method did not receive bipredicate Why not? What are the alternatives?

Solution

Where can you implement the solution through streamex Library:

StreamEx.ofPairs(prices,(p1,p2) -> p1 + p2 == 5 ? StreamEx.of(p1,p2) : StreamEx.empty())
            .flatMap(Function.identity())
            .forEach(price -> System.out.println(price));

You may also want to create your own classes to encapsulate pairs
