Done with OOPS concept in java 🤠. Thankyou Durga Sir

[mainank]

Thanks for making oops concept so easy to understand. It was like scary thing for me but your most comprehensive approach towards java language makes this concept a piece of cake for me. I have easily come one step closer towards making myself perfect in java language. Your contribution is highly appreciated and particularly me kind of poor student who can't afford to have coaching. Thanks once again and may! God give you immense energy so that you can achieve success in your endeavour.

[vipinmca]

Hi sir,

First of all, Thankyou so much for these awesome videos. I learnt a lot.

I saw all video of (Object Oriented Programming), I have some confusion regarding constructors concept.

1. If we are not creating no-args constructor in our class, then why compiler do this for us? and what if default constructor is not created by compiler?
2. why compiler add super() in constructor. what happens if compiler will not add it?
3. why we add private modifier to singleton class constructor. What goes wrong if it is public?


If possible please clear my doubts.

Thanks.

[KUNAL]

Sir, please upload the videos for design patterns in continuation with these ones..
thanks..:)
