Thank you so much for making this! It's been awhile since I first learned & use Java and now I have to re-learn it. You made this complex language a lot more understandable & approachable.

Great refresher for relearning Java. It's been a while since I coded in it. You went into easy to understand detailed explanations. Especially on OOP. Thank you so much for making this!

@Freecodecamp - please create an advanced java course and do a couple of projects as well in Java, Spring boot etc. kind request.

Thank you Farhan Hasin Chowdhury for a great course of Java!🙏

[bluesquare]

Thank you for making this Farhan. It has been a pleasure spending time with you!

In the ArrayLists part of the video, as of the the current time, you can use the set() method without using Integer.valueOf() just to set the value and Java will automatically figure it out. Take the example in the video, you can write it as .set(2, 30) and it works just fine. This goes the same for the contains() method.

I think the basic concepts are easy to find and learn. A lot of students needs good and detailed tutorial on OOP concepts.
Though you guys are the real W

I sat through and coded for 6 hours 30 minutes, along with you and i feel like i am on another level of understanding it now! You should be my Uni Professor :)

Done with this!!
Thank you Farhan sir!

Honestly, Freecodecamp has done so much in the decentralization of knowledge. Although, it seems to be there is a lack of Java content, specifically in the SpringBoot projects. But take my rant as a sidenote while I enjoy and digest this Java content. As always, freecodecamp rocks!!

[shotarcherz]

Im glad this is so new! Im taking my first java class in college!

It's nice see someone from Bangladesh doing great work in international plateform . I love your tutorial and Thanks you for doing this <3

Great video. Thanks freeCodeCamp and Farhan.Just one correction at 3:12:00, that doubling the arraylist is not always correct.For eg : if your input arraylist is [2, 4, 5, 1, 3, 6] then it will give [8, 4, 10, 2, 12, 6] because of the indexOf logic .(It doubles 2 to 4 in the first iteration and in the second iteration again doubles the 4 which actually was doubled from 2 rather than doubling the 4 at index 1)
