19:16 The instance of the ArrayList class is not aware of the Type as in run time, all the types are removed and Java treats everything as an object, which is termed as Type Erasure. The Generic Type is a compile time construct, it's just associated with the reference created to point at the object !!!!!!!!
1:04:51 List is an interface, its object can't be instantiated. We can only use List as Reference type (Reference to an Interface) & can create object (implement) ArrayList/LinkedList and other classes in the sub hierarchy.
my doubt is when i declare list l=new arraylist(); which is to hold only integer object but i when i try to add strings also no error is coming ,why its happening ???
Hi Madam, Please Provide me link or playlist of Full course of java program. I have Searched this tutorial in Great Learning channel but i did not find out this generics in java video. as i want to please help me Full Course of link or playlist channel. please help me, please help and consider me a student of you.
Concept of generic method is itself you can call the method with different argument types and the print statement written within that generic method is allowing that type of argument ( Integer type array passed to method ) got printed while transversing for loop.

great explanation
Thankyou for the explanation 🙂
Thanks so much for this good work
Thank you for great explanation
Thank you
Thank you so much mam !!
Expound about also object immutability
31:21 Generic method has return type T then what was void
Nice

Great video👍🏻
thank you :)
Could not understand handwriting until 26:29 therefore it is suggested to edit video to increase view count and introduce legible slides

34:44 very strange that b1 was of type String but it accepted int
yoo
yes, i am also confused on that
