Sir your hierarchy of explaining concepts is very precise and step-by-step... i wish my university professor had explained me these stuff in this way. Thank you sir^_^
sir its a humble request plzz ap jo b chapter pdate h uske bad usi video mei us chapter se related kuch programs b krwaiye so that hume sb aur jyada ache se smj aaye.. atleast 2-3 programs..
Great Sir !!! I was havind doubt in wrapper class , but after watching this video I found that my alldoubt was clear, even i was having more knowledge on wrapper class. Thank You Sir !!!
It would be great if you can explain a scenario where these are actually will be implemented for example when you are explaining what parseInt does also explain a scenario where it is actually being used
i would like to say big Thanks to your effort of teaching in simple way i have one suggetion though why don't you use an Eclipse in your demonstration. so you can also show an output to make easy to understand
valueOf() works by invoking the toString() method of the respective data type passed to valueOf(). Thus any object can be passed to valueOf(), and we would not get any error, as internally, toString() method would get invoked on that object.
Your lectures are very well explained but anyone who is new in programming needs some basic additional examples about every topic.As you have learnt java so well you can add some examples which you think will be helpful for the beginners.
But sir, if wrapper class is used as a solution to creating 100% OOP, and if parseXxx( ) and xxxValue( ) are actually meant to be used when primitive datatyped variables have been created, then the concept of 100% OOP will be destroyed again by the wrapper class itself...? int a= Integer.parseInt("123"); int c=i2.intValue( ); This has created 2 variables {a,c} using primitive datatype
Sir, we can also write Integer i1 = Integer.valueOf("123"); as Integer i1 = 123; so then what is the difference? And one more doubt Integer i1 = Integer.valueOf("123"); in this i1 is a reference object or is it instance(object) of Integer class? If it is reference object then before declaration we haven't used any special symbol like &(C++), So then how compiler will understand whether it is reference or instance of class. Please clarify my doubt.
In the ValueOf() function , the result is stored in the object of the Wrapper class whereas in parseInt() function the value is stored in the primitive data types
hello sir its very good lecture i like it and it is very useful but i want to learn more about parse() function so plz upload some videos of it. thanks sir regards, sunil jaiswal
sir aapne pichli video m to btaya hai ki int ko hum instance variable bolte hain mtlb object variable aur isme aapne btaya ki primitive datatype se bn ne wale objects nhi hote🤔🤔🤔
sir namaste, mera question ye hai ki valueOf to static method to iska object kaise bnaega jaisa aap video me keh rhe h .isko thoda or clerly smjhna tha.🙏
Actually, Java does the smart work here. This facility is provided by java to avoid compile-time error. Also, Integer i = 123; will work without any problem.

Great Sir !!! I was havind doubt in wrapper class , but after watching this video I found that my alldoubt was clear, even i was having more knowledge on wrapper class.
Thank You Sir !!!
Sir your videos are one of the best video available on TH-cam.
your teaching style is very clear..
I like your lectures...
Doing good job sir... but that would be more helpful towards learning if u upload some programs related to lessons.
You are doing an amazing job sir. Thankyou so much.
Jaane meri Jaaneman
And yes ...your teaching style is really good especially the rate of speech and crisp content on the topic.
the way of explanation is very good.hope all can easily understand.thank u sir..
helpful lecture sir, thanks
Sir u r so Great ! tnx so much.. love from Pakistan ...
maashA Allah sir g ap great hen....
Thank you!
This quarantine gonna produce a lot of programmers!
Valueof() is returning Integer and parseInt() returns int so what is difference????
You are genius. Your teaching style is also very good.
Thanks a lot sir. Aap students ke liye ek programming Messiah ho
Pls add related questions in description
1. valueOf:
static
saves a value to reference variable.
2. parsePrimitive:
e.g., parseInt
static
saves a value to primitive type.
It would be great if you can explain a scenario where these are actually will be implemented for example when you are explaining what parseInt does also explain a scenario where it is actually being used
bundle of thanks sir
well videos sir........bohat achi h ye aapki videos..... thanks
Thank you so much for providing such amazing quality.
i would like to say big Thanks to your effort of teaching in simple way i have one suggetion though why don't you use an Eclipse in your demonstration. so you can also show an output to make easy to understand
that a very useful vdo for me and my callics
Sir thank you so much for such video's , you teach the best !!!!!!!!!
Simply and seamlesly explaination
Video is to the point and very well explained sir.
Thank you for this. Wish you the best ahead!
Sir Jaise aapne C programming padhayi sabhi topics se related program same waise hi java mein bataiye
You teach very well of theory but I have one problem of programing.
Please Do something for programing.
That's so kind of you
Very nice
Sir apne bola valueof() static function h to ye object kaise bna rha h Integer class ka
Hna or object to new key word ki help se bnega na
valueOf() works by invoking the toString() method of the respective data type passed to valueOf().
Thus any object can be passed to valueOf(), and we would not get any error, as internally, toString() method would get invoked on that object.
sir i think in valueof .....O is capital ..great tutorial sir
Sir, as you r saying in this lecture that valueOf() is a static method so how can that method make an object of integer class? plzz tell...
Your lectures are very well explained but anyone who is new in programming needs some basic additional examples about every topic.As you have learnt java so well you can add some examples which you think will be helpful for the beginners.
the quality of service provided by sir can not be compared to anyone......
Nice
Sir if in "parseXxx" Xxx is a primitive type then it should be like "parseint" instead of "parseInt".
Sir value of is static how it can make object
Great job sir!!
Great work sir
sir ye videos aapko netbeans ya kisi or compiler pe run krwake bhi dikhaane chahiye the....
sir thanks for the videos but plzzz sir ap examples ko run bi kr ke dikhaya kijiye
amazing explaination sir superb....
air please update vedios in advance Java topics like servlet.......
But sir, if wrapper class is used as a solution to creating 100% OOP, and if parseXxx( ) and xxxValue( ) are actually meant to be used when primitive datatyped variables have been created, then the concept of 100% OOP will be destroyed again by the wrapper class itself...?
int a= Integer.parseInt("123");
int c=i2.intValue( );
This has created 2 variables {a,c} using primitive datatype
No cause it is using the object made by wrapper class so it isn't destroying Concept of OOP..thank me later
Not necessary to use int he just used it for simplicity. Telling the functionality of parseInt()
sir ,
can only through your video lecture we can lean java or require some book if book require then please tell me which book prefer for java .
may you share any example for double type unboxing and double to string conversion.
Thanks so much sir easy to learn this topic
Sir, we can also write
Integer i1 = Integer.valueOf("123");
as
Integer i1 = 123;
so then what is the difference?
And one more doubt
Integer i1 = Integer.valueOf("123");
in this i1 is a reference object or is it instance(object) of Integer class?
If it is reference object then before declaration we haven't used any special symbol like &(C++), So then how compiler will understand whether it is reference or instance of class.
Please clarify my doubt.
Integer.i1 hona chaiye tha na ??
Agr smjh agya to reply krdena bhai
please upload some related questions to practice so that we can learn much better :)
sir, whats the difference between valueOf() and parseInt() method they appear to do exactly the same thing to me .
please explain.
In the ValueOf() function , the result is stored in the object of the Wrapper class whereas in parseInt() function the value is stored in the primitive data types
bilkul pasand aare he
hello sir
its very good lecture i like it and it is very useful but i want to learn more about parse() function so plz upload some videos of it.

Sir agar Integer ek class hai to usse hum object bhi to create kr skte hai n??
Hi Saurabh sir,
Will you please share selenium vedio as well?
Awesome, thanks a lot.!!!
Sir, will you please compile this programme.
Koi error aa rahi hai kya ... Actually mera bhi nhi ho raha compile
sir aapne pichli video m to btaya hai ki int ko hum instance variable bolte hain mtlb object variable aur isme aapne btaya ki primitive datatype se bn ne wale objects nhi hote🤔🤔🤔
doubt sir✋✋
you are so ammazingly explainned ...thank you so much sir
Thank You So Much Sir❤️
Sir valueOf() agar static function hai to object kaise bana ra hai Integer class ka?
+Shrish Chamoli who says static function can not make objects.
Concept is --- you need not to make an object to call static function
valueOf() method means autoboxing...if we only write
Integer i=10; then after compilation this will be replaced with
Integer i=Integer.valueOf(10);
@@javabysaurabhshuklasir3459 sir object to new keyword ki help se banta hai na java me.
Can U please explain wrapping & unwrapping in terms of this concept?
Sir i1 is the object of Integer class? but how we are not using new keyword here...
because it is static in nature , check Static syntax for better understanding...
Because I think Integer is predefined class already in Java so no need to again allocate memory using new keyword...
sir kya parse function wrapper class se primtive me jaane ke liye use hota hai
thank u so much sir its too helpful for me
Good..
U R legend sir❤
sir thanks teaching us i want more videos
Hello! Sir I want to know that what is the need of wrapper class if i can achieve same objective using primitive data types
to achieve 100 % object oriented paradigm
I have a question..what if we write Integer i=0;
System.out.print(a);
then also the program is working.
what does this mean?
please try to reply sir
sper sir
Sir ye program prui trhe se object oriented nhi h ? Kyo ki isme int s to primitive data type h ? Pls give reply sir and any one
thanks saurabh shulla bhai
sir , we should have to import java.lang.* or not in this class
What is difference between int or Integer?
Thanku sir for supporting ...
Sir we can make "int" type (primitive) datatype Private, protected,publicHow its possible in wrapper class objects ?
what is the difference between valueof() and parsexxx()
sir valueof() bhi whi kaam kr rha jo parseXxx() to dono me difference kya h
nice videos
Hello sir apne isse phele ke language me kaha tha ki object new keyword se banta he to phir hamne wrapper me new keyword ka use kyu nahi kiya
Sir ,i1 is a object or a reference variable..and can i write [int i1] at the place of [Integer i1]..?
i1 is a reference variable
Why only Arguments is passed as string
Be more precise with upper and lower case syntax like in xxxvalue() the 'v' is capital but in your vedio it's small.
Where you explain parameter passing in methods?
then what is the difference between parse and valueof
what is the difference between int and Integer
int is a data type........but Integer is a class
Why do we use wrapper class when similar work can also be done with primitive datatypes
Sir, how to take input from user in wrapped class.
sir me pochna chata ho ki app ne jo java ke 75 video's hai ye complete core java h.pleas ansewer
sir namaste, mera question ye hai ki valueOf to static method to iska object kaise bnaega jaisa aap video me keh rhe h .isko thoda or clerly smjhna tha.🙏
Sir ne classname.method ese value of ko bulaya Integer.valueOf()
Or yah object return karta hai
i1 yah object hai
i did not understand where we will be able to use it.
Sir, explain wrapper practically
Sir your sound is slow so please increase it
sir... parseInt aur intValue me kya differnce hai??????
parseInt converts the string into int.......nd intvalue is instance method....means convert Integer into int
Sir plz progrma ko run kijie ...
Integer i = Integer.valueof("123");
Ye line se pehle aapne
Integer i=new Integer() ;
Kyu nahi likha ?
Actually, Java does the smart work here.
This facility is provided by java to avoid compile-time error.
Also, Integer i = 123; will work without any problem.
In valueOf() O is capital!
Yes...so?
Thankyou sir❤❤🙏🙏
Sir , you told that in wrapper class primitive type is written in capital letters . But sir praise is written in small letters why??
Sir aap konse place per rahte ho
Isn't int a wrong at 9:21 because in java wrapper class integer is used instead of int...!!!!!!!!!
