Hi navin i don't see how forEach method is related ro Stream Api as we haven't used stream() method and the method reference parameter also has nothing to do with Stream Api. forEach is just a default method added in Iterable interface. Am I wrong? Please answer.

i dont understand why is that Collection.sort is working.? isn't there should be List.sort instead?

[kamaldeepak]

hi sir in the video at 4.47 you write List<Integer>
but you sort the values using Collection.sort(values) why?

[AbdulJalil-lnle]

List<Integer> Values=new ArrayList<Integer>();

Hello Sir, I need some help. The eclipse ide is not recognizing the list interface. It is stating that the list is not generic when i am mentioning the integer type generic. Do i need to change the compiler settings?

Collection is an Interface how list can extends collection it supposed to be implements right?

[mrclassy]

Why list interface is used for declaring an arraylist

[jonsnow]

Sir what is this?
int iArr[] = {2, 1, 9, 6, 4};

for (int number : iArr) {
System.out.println("Number = " + number);
}

Arrays.sort(iArr);
What is Arrays here?

[aishikbhattacharya]

[AjayKumar-zhyt]
