[waqarahmad]

what is the main benefit of converting primitve to obj and vice versa?

[TheRiishii]

Why we convert primitive to wrapper and vice versa?

[shivamkamdi]

Thank u sir, thanks a lot for such excellent video lecture series.😊🙏🙏

[gokuspiritbomb]

*5:34** How "i" is object ??? It is referance variable right ?*

[Deceiveryaya]

Do we have to give initial value to our primitves during boxing ? what if we want to use scanner class and assign different value to both prim type and obj type ??

[SanathanDharmaa]

here in the primitive to wrapper the object should be "ab"?.why did u mentioned "i" as object?

[kannank]

what ide is that in which u run ur programs sir?Pls comment below so.

[pawanprakashh]

Sir where we can find the videos for enumeration, autoboxing and annotations videos ???

[umadivvela]

Y&how do compiler will write automatically ???

[artun]

Sir, how can I Unbox the Integer[][] type to int[][] ?, in other words how can i transform Integer[][] and int[][] one another?

[ankitamishra]

Sir, can you please illustrate some examples of character type wrapper class. It is very confusing. Thank you

[vipinyadav]

sir, as u said that these wrapper classes are present in java.lang package then why didn't we imported that pakage in our program.

And while converting wrapper to primitive we directly assigned the value of integer to an object of class integer without creating it .
we did this...
int i=100;
Integer obj1= Integer.valueof(i);
why didn't we did it like this
int i=100;
Integer obj1= new Integer();
obj1= obj.valueof(i);

[avijain]

getting error like integer is deprecated..what does that mean

[rakeshparmar]

Sir, please explain why wrapper class is required?
And what is advantage of Wrapper class...
