About Question enthuware.ocpjp.v8.2.1850 :

Hi Paul,
After working on this code, I see that streams don´t change the original collection object. Streams work on the object, but they are not able to change this original object. Am I right?

I just saw that streams can change the original collection object if the stream invoke a method able to change the object, like setter methods:
In another Enthuware question, enthuware.ocpjp.v8.2.1872:

Code: Select all

s.forEach(b->b.setPrice(10.0));// this setPrice will change the original object.

You are changing the property of an object of a Stream. Not the stream itself.
