If you have any doubt....🙃🙃 don't worry we will cover it in Object Oriented Programming😉

Amazing String session, now will spend the rest of the weekend doing leetcode questions after watching these lectures it makes me really confident

-->
+ operator can be only used if one of them is string

complex object + string || primitive + string ---> object will be convert to string using to string method in println.

1:03:43 -> new object created everytime
1:11:54

String Converting into character array 1:13:20

1:13:26

Original one is not changed, new object is created. 1:13:56

Index of 1:14:40
Split array 1:16:59

Palindrome 1:24:43

The charming thing about your tutorial is even if the topic is known to me, I gather some new, in depth knowledge every time.

What an amazing work you are doing Kunal. I wish I had a mentor like you during my first year of engineering. Learning DSA from your bootcamp and it's amazing. Thank you so much Kunal. You are amazing❤️

Watching this video, 1.5hour flew by and felt like just 10mins content! That's how teaching is supposed to be! Doesn't make you feel bored.

[vismayagowda]

[nirvanaseeker]

Your way of teaching has made me believe that yeah i can also code. Thankyou for sharing your knowledge. You are a awesome teacher.

[harshshiyani]

I learned in java at the level of JSP and servlets.
So, I confidently tell you that if you want to learn String and StringBuilder classes very deeply, you are at the right place.
Keep Learning.
Kunal you are doing great work, Keep it up.

There are some person who doesn't wann good of tier 2 or 3 student... your video was so helpful to choose what to study and from where to study and where will we just waste our please don't remove such pure content....Your videos save lots of time of a tier 3 engineering student specially your live and guidance videos.. it's humble request because of some person, u just don't change your way of guidance.. we need your guidance are one of those teacher who speaks truthfully, that too without being afraid of anyone..please don't give much importance of haters.. please 🙏🙏🙏🙏🙏🙏🙏

[sachinmulgir]

following your videos since a week and haveee done someee great job here...the best part is that you cover all the topics in depth, like memory allcoation, the internal working of the program, what classes and objects java has in it and how it helps us to perform any action. like in this video only the way you've explained the concept of println and how it calls toString() and our output is printed. Just wow man....keep it that i found your course on youtube. thanks a

[yatharthnigamecef]

So much information in one video.
Had to make a lot of notes as each line felt important 😂.
Awesome lecture.
