Ab toh sach bolde

[@amritpaudel8204]

To all the new comers : In 30:56 when Kunal says in Java there is no such thing as pass by reference he means that there is no any way by which we can pass the primitive data types as reference in java. For example in C++ we had & and * operators by which we could pass the memory address of any variable we want ( even primitive variables like int, char, float etc ) and we can always achieve pass by reference but in java there are no such & and * operators. But in java we do have certain reference variables like classes, arrays. Since they are already a reference variable passing them through function might look like a pass by reference but that is because the variable name already is a reference to data in heap memory. So DO NOT BE CONFUSED

[@ashwathks784]

Thank you

[@abhinav2004]

Thanks Amrit

[@abhishekranjan1523]

in call by value example when he pass the primitive value to the function he tells that here we not change the value of the object we create the new object this is wrong and he didn't explain right

Very nice explanation, i am having more that 13 years of experience in java but still watching just to learn how you are teaching and explaining... very helpful for any new person who wants to understand java. Good job, much appreciated ... keep it up...as of now i have forwarded your chhanal link to more than 20 freshers... nice contribution towards community...

[@ajitpandey4265]

One more interesting observation about VarArgs: If you have 2 functions with the same name (i.e you are overloading a function) eg:- fun(int p,int q) and fun(int ...v) and if you call fun(10, 20) from the main function then function accepting the exact number of parameters( fun(int p, int q) in this case ) will be executed and VarArg function( fun(int ...v) in this case) will be ignored. hope it helps! :)

[@Arjun8BPCracker]

Nice observation

[@vrashabhsontakke7282]

So, it means if we call fun(10, 20, 30) or fun(10), then the fun( int ....v) will be executed, right.

I just found the best way to understand scope. So think the outer variables as the king and the inner variables in a block or loop to be the common people. The king can visit the common peoples home at any time but common peoples can't visit the king usually. It's something I came up in my mind & thought would be helpful for you.

at 45:00 whosover is having doubt in change value read this: like in the video he has said that pass by value works on primitve datatypes like string, int char byte etc,whereas objects and stuffs like array which is not a primitive datatypes, its a reference variable(collection of ints or any data type that I declare) so that's why the value of arr[0] got changed since array itself was the reference.hope this might help

At 1:22:14, prime number solution - do we really need to write -> return c * c > n at line number 24 or we can simply return true as code flow will reach on line 24 only when while boolean clause is false, thus c * c > n will be always true when flow reaches line 24. Thoughts ?

in case anyone still confused about change value part, just remember methods do activities and NOT implementations....so in case of int array, the method is doing the activity of putting the value of 99 in 0 index ,,where as in case of string name , it is trying to implement the value,,,,thanks

then why did it not change for swapping also? It is also doing an activities.

I would like to correct Kunal sir, He somehow interpreted initialization and declaration as same but declaration is telling the java compiler what type of variable I want (which means datatype of the variable). initialization is storing value or referring to object (Note :::primitive data types stores in stack memory they do not refer particularly in java whereas python differs, referring datatype do refer to an object.)
