@ 59:15 - I think final variables can be initialised in blocks as well, i.e. static and non static blocks depending on the type of variable.

Your interview question videos are quite informative ma'am. Thank you for such valuable lessons.

Excellent, but what is the source of your knowledge. I knew all the answers except the last one but still would love to learn more. Is there any class or session I can join. Your way of explaining things is really clear. I have Approx 7 years of experience 👀🥲 and also going through DSA and System design. The most frustrating thing is when we need to convert Character to char or char to character just to perform some basic mathematics and comparison when using the collections such as ArrayList while solving any problem. Although java itself does the type conversion but here many cases it fails and we need to find a work around.
