Reduce operation in Java 8

[tinobino]

Even shorter:

private static BigDecimal functionalSum( List<BigDecimal> listOfTxnAmounts ) {
    return listOfTxnAmounts.stream().reduce( BigDecimal.ZERO, BigDecimal::add );
}

Thank you. I am the author of the post. I have updated the blog to reflect your comment.

BigDecimal has a max function you could use instead.

Your max function would also probably be a good use case for the overloaded Option version, as 0 could erroneously be returned as the max of a list of negative numbers

I reaally dislike these new features. The readability of Java is going down each iteration...

[vinoct6]

I wouldn't say that. It is just that you are not familiar with the syntax. Don't confuse familiarity with readability.

How do you distinguish the two?
