I request u to post more videos like this....thanks to you i am able explain the logic clearly in my TCS interview 😁 and also got selected...thank you so much bro❤️

Can you do programs and its output for all basic programs in java and also of different way of approaching.......

[@godsin924]

what if we take n =2 then 2%2 = 0 so will it not give output as not prime

[@40_shreyanbanerjee28]

Thanks.. but the output should be a little bit more specified !

Thank you so much sir it's helping me lot and now program Is very easy to me when u explained it clearly..

what will be the output for 1 and 2 ?

bro why did you used util package . Can you please explain

[@girlstjohnian]

Bro you pick up such good topics for your video, others just explain the concept and go forth, but here, you know like literally this question came in my exam, and coz of you! I got full marks!!

[@BTechComputerScience]

So good to hear😊❤ Keep doing great👍

[@mr.badluck9521]

If we take 1 as input then it is showing true as a prime number but 1 is not prime number sir so it should be false at the output .

[@malavikasadasivan8291]

What is the output if n=4 can you show

[@vlogman5657]

thanks man! but the package prime; is really hitting me i dont get it right on blue j please respond fast

[@jaganjagan7958]

I think We can't find 2 as a prime number by this program..please do check with 2

[@aegon199]

9 is not a prime number because it's multiple by 3, 1, 9..

[@aegon199]

Sorry

[@hussainbasha3794]

Good explanation

[@gaddamprudhvi9737]

nice explanation

[@Moonart.shorts]

Thank you❣️

[@MadhuSudhan-um2lm]

beautiful answer but there are one mistake bro , if you are entered n = 1; output is true , this is wrong step

[@chiranjeevinarada1704]

Bro Please do video on SQL queries plz plz

[@saleemsadat6557]

good explanation. However, your formula will disregard negative numbers. For example if you put -11, it will print true. But we know minus 11 is not prime.

[@BTechComputerScience]

Thanks for ur input, a 'if' statement before the loop to check input criteria would prevent it. Yes I didn't cover all test cases. Just the basics

[@chandandastanti9346]

Before for loop add one if(n

[@khushbusahani579]

Thankyou so much now I can clearly understand how to print prime no. What's the logic behind this program ☀️💯

but 2 is considered as a prime number the code will not be accurate here

Kaisaaa woo kaisa

[@sweetani9378]

Okay bro check n=2

[@offthehook5042]

I want with inheritance

[@gaurav1005]

why we are running it from i=2 in for loop ?

[@BTechComputerScience]

Since all numbers are divisible by 1, we are avoiding it to save some computational time. Also the given number will always be divisible by 1 and N and we need not care, all we have to see is if any other between 1 and N divides N to prove its NOT PRIME.

[@gaurav1005]

@@BTechComputerScience thank you soo much sir

dear sir; i got revese output Which means that which are all prime number that show all false ,which are all not prime number that show true

please explain sir i have confusion

Mayb u r changing ur boolean variable wrongly, please check with ur boolean variable and where u r making it false or true... if still u r unable to fix it, post ur code in the comment, I ll help u out😊

[@BTechComputerScience]

@@NaveenKumar-oc8bz ur break statement should be inside 'if' ... u missed the '{' and '}' Since ur break statement is inside for loop and not the 'if' statement, ur loop is breaking at first iteration.

sir why you can not take 9 then u will took 9 it will print is a prime but it is not a prime

[@BTechComputerScience]

It will not print 9 as prime 😊

Bro good explanation. But 0 and 1 are not prime numbers if I give input as 1 or 0 for above program it will be printed as True. so please correct it

[@BTechComputerScience]

I have explained at basic level, I have not solved the edge test cases, students should identify the edge test cases like u did and try to solve it. That's how we learn!

In.. Your code we take... 2 then.. Its show not prime.. Number but 2 is prime number... Know... Then.. What we do

Think about the logic, I know u can solve it! I just gave the basic logic for the program 😊

[@WolfPaul]

wow.

[@LYJManchesterUnited]

if you enter 0 or 1 it says it's a prime number

[@BTechComputerScience]

It's great that u have noticed this, 0 and 1 are neither prime nor composite, for beginner level this program is fine. I really appreciate it, after roughly 5.8k views, u are the first person to notice. Just add this before the 'for' loop if(n == 0 || n == 1) { System.out.print("Neither prime nor composite"); System.exit(0); }

[@roggamerg531gt]

what about 0 and 1

[@proxy5061]

Yess if(n == 0 || n == 1){ It's not a prime } Else { The vedio logic , the condition inside for loop must be n/2 }

What if number is 2

[@BTechComputerScience]

Since 2 is divisible by 1 and the number itself (2), it is a prime number :)

[@giridatta1525]

how to pass n=2 into loop?

[@anjeshwar1]

this program explains even or odd not prime. Give input as 9,15 it gives true but 9,15 are not prime numbers. sorry to say, check the programs with different inputs and upload bro. Most people doesn't checks it and follows the programs blindly.
