Sir you made me understand collections concept in very little time. Thanks a lot. I am now comfortable enough to use collections in the DSA questions and other harder topics in Java. Waiting for more videos in Java series. thanks once again.

In iterator example, why do we need to have OurGenericList inside the inner class since we can use the outer class's variable items? Instead of index < list.size cant we use index < items.length ?

Very well explained, thanks for sharing quality stuff, can you share the notes related to this entire video if available please? As well as share some resources based on Wrappper class, boxing,unboxing,Comparator,Comparable interfaces,toString methods, if possible. Hoping to see some tutorials on OOPS in java from you. Do we go for Comparable interface only in case of custom classes where we need comparison strategy whereas we go for Comparator interface when we want to change existing order of comparison?

The time to traverse the LinkedHashMap is proportional to the size as it maintains the order on insertion in the form of linked list and to get the value as per the matching key(hashCode() of the key) it has to traverse linked list linearly one by on which makes it O(n)[n->size of the linked List] complexity.Here the size is the no.of entries in the map not the the capacity to hold the max no.of elements
