You are one of the few that shows ifPresent and isPresent in a Collection using Optional. Others are just using Strings or Integers. This is the real stuff. Thanks

Could you please show how to do code coverage using mockito for this Optional case?

ArrayList<String> list=new ArrayList<>();
list.add("Mango");
list.add("Apple");
list.add("Banana");
list.add("Grapes");

Optional<ArrayList<String>>

list1.filter((item)->{ System.out.println(item); return true;}) or ist1.map((item)->{ System.out.println(item); return item;})

is there any way with filter and map of optional to iterate one by one on array element when i using this it returning me the whole array.
