Functional Programming in Java, Second Edition: Chapter 1, p.15, a little note
On page 15, we read:
In this example we’re sending a function,
price -> price * 0.9, as an argument tomapToDoubleThe function being passed is created just in time, at the point of call to the higher-order functionmapToDouble.
As a simple clarification, one might write:
In this example we’re sending a function,
price -> price * 0.9, as an argument tomapToDoubleThe function being passed is created just in time (at least conceptually - it really is compiled into executable code and a class (if necessary) at compile time), at the point of call to the higher-order functionmapToDouble.
