Very useful content from beginner level to few advanced topics in a simple and clear with cool pace.I have completed entire video and practised coding simultaneously. It would be really great if you can make next advanced level video on Collections bro.
Hi Ramesh, this is an excellent course on collection framework , highly recommended for freshers and it will be refresh for experienced professionals. Thank you sooo much for your great efforts. Kindly add advanced collection concepts. I started learning java 8 features from your 4: hours video after completing that i will start spring framework course from your Udemy, i bought it today ❤😊😊
Completed this course, well explained with theory and coding example Must watch tutorial to learn and Java collections api for beginners and exp 👍 Thank you much
Hi, i am beginner in Collections, your video really helped me a lot.. I would like to know whether you have posted any videos for PriorityQueue, TreeMap and TreeSet.
what is good practice 1.using List interface to create -> List List arr=new ArrayList() (here we wont be able to accedd the methords of arraylist) 2. using ArrayList to create ArrayList -> ArrayList List arr=new ArrayList() (so that we can access the methords of ArrayList)
Thanks sir! you are so great person. Finally i understand clearly difference between Arraylist and Linkedlist. I follow your videos mostly related with the spring boot. Thanks a lot sir
Best video found in terms of Java implementation. Really good. Thanks for creating it. Is it possible for you to create for Abstraction and Interface with lot of examples.
You are awesome man! I really appreciate your work. I hope you do not mind critic. I think it was good to mention about hash function and equals during using custom class in a HashMap. Thanks for your time and courses.
Very educational and enjoyable to watch. Concepts are explained clearly and with good examples. Just need to do some practice to remember these concepts.
If by default size of an Array list is 10 , why the size of ArrayList is displayed as 0 and not 10 , if we try to print the size just after declaring it.
Size is different and capacity is different. ArrayList has initial capacity of 10. It means ArrayList can store 10 elements and then it will increase the capacity as needed. Size means the actual elements stored in ArrayList. For example if you add 3 elements then the size is 3.
Hv u shown all those internal like how hashmap works ,how arraylist increase it size ,or its just a program practice session . Asking before watching ?
