Functional Programming in Java, Second Edition: mapToInt() referenced instead of mapToDouble() (page 21)

@venkats

On page 21:

For each price from the prices list that passes through the filter(), the mapToInt() method invokes the provided lambda expression to transform the given price to a discounted price.

Reference to mapToInt() is incorrect, as on the previous page (Page 20) to example code contains mapToDouble() which makes the code working.

First Post!
