Lecture 11 P7

[Guo-Yujia]

Summary

For page 7 in lecture 11, some alternative ways are provided to replace forEach(), can someone give some example on how we should use forEachOrdered and CopyOnWriteArrayList. By the way, may I clarify that does the encountered order mean the order of elements being passed into the function?

Screenshots (if any):

To add on to the question, what is the difference between collect, collector and collectors?

Encounter order is the order in which the Stream encounters data. So, it is wrong to say it is the order in which the elements are added into the function.

To add on to the question, what is the difference between collect, collector and collectors?

Collect is a method. Collector is an interface and Collectors is the class that implements the Collector interface.
