Collection Sort Method behaviour explored ..extended part of list.sort video. #arraylist #sorting

#arraylist #sorting #coding #java #corejavatutorial This learning videos is on Collections.sort() method and extended part of earlier video list.sort ( https://www.youtube.com/watch?v=qCFmMn4qinQ ). I explore here how to sort Wrapper Data type, String and Custom Classes like Employee, Students etc. How Comparable play a vital hidden role here to sort elements. And why it is mandatory to implement Comparable while using this sort() method. Also see sorting in reverse many by using Comparator.reverseOrder() and reversed() method. Why two ways to reverse elements . Very good learning I experince I got after this. Does not matter how much I know before this. It added more clarity on my previous understandings. #arraylist #sorting #coding #java #corejavatutorial
