Interview Question : Compare Two Integer Numbers (Integer Caching) in

[@amitkumarshinde4090]

Hey man u r really awesome, i have never been explained this concept Or never heard this concept. Really thankfull to you man.. Keep rocking

[@ankittripathi6150]

Sir I did have 3 years of experience in Vmware but after learning through your channel only i have switched to testing by showing the same 3 years experience in that. Your way of teaching is excellent.

[@saikrishnagaddam8857]

Bro are you serious?

[@priteshms]

I never heard about this concept. Learnt something new. Thank you so much Naveen for all your efforts.

[@SameerKumar-yu1xi]

I will not comment thx for the contents that Naveen sir posting... Bcz he is doing it and helping in thankless manner... Just appreciating his hardwork and for motivating us🙌🙌🙌

[@durgaprasad4648]

Thanks bro for making us Technicaly strong.

[@nikhildandge8609]

Also , this caching concept is not available for Float and Double . ( because between 0 and 1, there infinite values that lie within the range and can't decide which is the most common range used) I liked the video very much @naveen . Thank you very much

[@madhuriparjane3054]

Hello Naveen, you are simply outstanding in explaining the important and complex concepts..Really like the way you put the things in short, crisp but understandable manner. Thanks for this awesome work.😊

[@suryajit7]

thanks man - I will ask this question in my interviews now

[@amitkumarshinde4090]

I will definitely share ur videos everywhere

[@raji1358]

You are awesome because I learnt a lot from you.

[@riteshranjanmishra967]

Thank you Naveen for covering important interview questions

[@syedafarzana960]

You are the best sir plz explain all the recent java coding questions asked in interview

[@sksingh329]

So integer caching works in range of Byte data type.. It was intresting. Thanks for sharing

[@AshokKumar-ye3zc]

Very informative video. Where can we use this concept in the framework?

[@sridharlanka2721]

Informative & truly interesting 🧐

Hi Naveen, Any tips for Kafka automation? Can you suggest me some tools to Test Kafka.

[@nikhilgayki8807]

Thanks naveen...

[@himanshupokhriyal6883]

Output -) both are equal because data is same in both variable num1, num2

[@pradeeppattar8862]

Yesterday I got this type of question.

[@eduartzina]

Hello, very good knowledge here. in my case, I had a situation of : taken two arrays. array 1 = 5 and array2 = 2. the question was How to compare every index in the array and how to find how much should I add to array1 to be equal to array2? it was a tricky one and to me, this was the first time having to work with two arrays and compare values. How will you approach this situation?

[@nilstoned7593]

int[] arr1 = {1,2,3,4,5}, arr2 = {6,7}; int sizeDifference = 0; if (arr1.length > arr2.length) { sizeDifference = arr1.length - arr2.length; System.out.println("Items to be added in Array2 : " + sizeDifference); } else { sizeDifference = arr2.length - arr1.length; System.out.println("Items to be added in Array1 : " + sizeDifference); }

Hello Naveen, Greetings!!! I was trying this scenario in my system and it works as mentioned in the video.. But i tried comparing Integer a = 123 and int b = 123. In this case it matches and showing true as results... Also tried out of the bond number for integer caching ie 130 or any number outside the range.... It was matching.... Could you pls explain

[@VipinDahiya89]

concept is for comparing two object and in second you are using int var not object

[@anjalimurkute1378]

Thanks a lot ..🙏

[@vishal252526]

Hi Naveen, could you please explain below scenrio. Integer i=300; sout(i==i) ; output-> true why it is not false???

[@balachandar6206]

Both I are pointing same variable

[@Erlisch1337]

oh its a Java thing...that explains why Ive never heard of this

[@naveenautomationlabs]

Yeah that's the hidden concept of java :)

[@rajatprajapati7140]

But range for int is larger than - 128 to 127.Then why does it give true only for - 128 to 127 ?

[@sreevidyarejeesh8695]

[@murahariraofam6473]

What is the purpose of integer caching?

[@rayinimadhu]

Sir my name is Madhu I'm Complet my Degree BCOM camarce how to came IT SOFTWARE side frst which course lm luarn...... please give me a gidence..

[@Viplove_QA_SDET]

👍👍👍❤️

[@muralikrishnap4337]

What is auto box

[@kathiresanm4280]

-128 to 127 is a range of byte data type then why the Integer is compared byte range

[@sayhifive2415]

But @Naveenautomationlab You still comparing references not values. So no point of values are being in range or out of range.

[@naveenautomationlabs]

No it matters. Check the full video when you go out of range of integer Cache it will give you false. So range matters here.

[@sauravMAitra96]

@@naveenautomationlabs if i use long then it will be right .. isn't it?

[@sonatejas7224]

all wrapper classes override toString() to return value of the object the reference variable is pointing to

[@rivermartinez107]

What happens if you use .equals()?

[@weirdspecie6356]

You have to rewrite it with string cuz .equals doesnt work on int

[@chintulovers]

Is this applicable for double

[@ManishKumar-qx1kh]

All wrapper classes come with caching but remember u can use caching only when u r using either primitive assignment or using valueof() method. If u are using new keyword while creating the object then it won't work.

[@blazegaming3810]

Idk what ur java application is doing my java application even show results as equal on 300000 comparing on both integers. I have cross-check by giving other integer values but it always shows same unless both integers r different. Idk what ur machine is doing.

[@naveenautomationlabs]

Are you sure ? Which jdk version you are using? Can you paste your code here?

[@blazegaming3810]

@@naveenautomationlabs okay so old version will show different result??? My java version shows 11.0.1

Integer Caching got added after 1.5 only. Make sure you are using Integer not int.

My question is not "what actually is integer caching". My question is, where do you even find this information ? In my 7 years of studying Java and I've never even heard of this before. O_O

[@naveenautomationlabs]

This question was asked to me once at the time of interview few years back.
