ArrayList vs Vector || Collection Framework in java || Java interview preparation

java interview preparation// ArrayList vs vector in Java is one of the most common questions asked in the interview and it’s very easy to answer all the differences but the problem comes when the interviewer starts asking you counter questions on your statement. This video is designed to answer all those counter questions. So by the end of this video, you will not only master the differences between ArrayList and vector but also you will learn to answer questions on CopyOnArrayList, ArrayList and Vector performance in a multithreading environment, concurrent modification exception scenario, java iterator and the internal of ArrayList and vector.

If you are new to the collection framework, I recommend you to watch the ArrayList beginner's introduction video by clicking the link below.

Hello sir, I'm 4th year engineering student and what i actually feel is these types of discussion missing in colleges.... Great learning from this video tutorial and i would like to thank you again and again for your effort....

If possible please create a similar session for multithreading.
Thanks

Hi Sir..I am u r new subscriber..i like u r teaching.The way u explained is easy to understand who don't know Java also.

[PradipYogi]

I found from java doc :
A structural modification is any operation that adds or deletes one or more mappings;

I think adding element is also structural change.

[addadadileepvarma]

Bro the way you present the subject that comes with inbuilt talent eagerly waiting for spring boot videos...

[ShubhamSingh-gxuf]

[sureshrayudu]

My Understandings
Marker Interface is the gives permissions to jvm to perform respective tasks with the object
Arraylist and Vector good for search operations, Because they implemented RandomAccess interface
Difference between Arraylist & Vector
1.Arraylist is not thread safe, but vector
2.Vector is legacy class, but arraylist not
3.Arraylist runtime capacity increased 50%. but vector 100%
4.Arraylist not use of Enumuration, but Vector
Offtopic QA
ListIterator is used only for list interface implemented classes only

[santhoshchandran]

Abhilash, can you make video for. Multithreading concept, it's confusing little bit, if you makr video I can understood easily

[Saravanan-ljso]

Great start.Please post more core vedio.

[AbhishekSharma-yqjn]

Array List allows duplicates or not allows duplicates?
