Now 32 out of 113.... 😊 Notes + video + explaination in easiest way = No doubt all clear 👍👍👍❤️🙏

[@nayanrajchalisha4736]

It's been 38 days since I have started learning, some days were too difficult for me to concentrate but still I'm on the go untill I finish this whole playlist and anyone learning or has just started or whoever gonna start in future, we all gonna make it. Take rest, take your own time but don't quit.

Wow!!!!... Amazing Harry bhai.. All concepts cleared. I came here after listening so called paid course lectures.. You are doing amazing work.. i have taken printouts of all your notes & they are helping me a lot while doing this java course. God bless you Harry bhai..!

[@hwaiting3573]

11:45 Change function will update the value of arr at index 0 because when we pass array to function/method it will actually pass the address of the value , therefore it is call by reference and it will definitely change the value of array at index 0 and print 98

[@karthikramkoru]

Tq bhai now I understood

[@ranvirkumar1472]

thanks bhai.😇

[@TabraizKhan-iv1cl]

If thats the case then for the integer , we passed x which is reference for 45 ,shouldn't a get x and x is the address of 45 so it should change based on your logic right..? I listened to it many times but couldn't understand it properly. I would appreciate you if you could elaborate it for me

[@bothighlights4179]

@@TabraizKhan-iv1cl suppose you have an array which is array1 = {1,2,3,4} and have a variable, int x = 6 so if you print the variable x it will give you 6 : system.out.println(x) = 6 and when you print the array it will give you the address of the array like this : [I@4517d9a3 so when you're passing x (int variable) in a method the thing you're passing is 6, because x = 6 you are not passing the address or reference of int x but when you're passing an array you are not passing the integers in array but the address of the array : [I@4517d9a3 and because you're passing the address of array the method is changing the actual array not a copy. in int x = 6 case you are passing 6 not the address of x that's why it is changing the copy not the actual x I hope you understood i can further help you if you didn't understand

@harry 21:44 You said method overloading cannot be performed by chnaging the return type but in your source code site you have mentioned it can be perfomed by changing the return type. Please clear the confusion.

[@parthsharma4996]

I have seen all your c and c++ playlist videos good going dude And thanks a lot for helping collage students like me from these videos

[@roxyisthebestwaifu712]

12:07 It will print 98. The value of array is changed because the reference of array is passed to the function. It didn't change during the integer because while passing an integer, the value was passed to the method.

[@TabraizKhan-iv1cl]

How is that same case then. He said it in the video that for integer it is no different compared to arra

[@allcoverd1708]

Thanka for coding classes you are the best programming teacher

[@gold8780]

In the example of (12:00), *value* is changed because "array" is not a primitive data type. (Harry said it previously that, this happens with primitive data types only). Same thing happens in integer as well as array, but in case of array only the reference is copied. Hope you are getting the point! It's alright if you got it wrong. Even I got it wrong at first 🙃

[@zainabkazi4102]

i rewind the video thrice but still not able to understand the difference in call by value n call by reference

[@atifasadkhan]

@@zainabkazi4102 inshort the value changed for variables because they are premetive data type but array is not premetive data type so you were able to change !!! premetive data types are (Boolean, char, byte, int, short, long, float, and double.)

[@MAD2ON_Talkroaster]

​@@atifasadkhanbut we can change the value of primitive data type through call by reference.

[@harshvardhanshinde9648]

11:51 Yes the value will change... As we are passing the name of array which is actually the base address of the array

thanks bro for teaching in very easy words .

[@Epinephrine_21]

12:10 list items can be changed with functions

[@xpert__ngel8857]

Harry Bhai your teaching techniques are awesome!!!

[@eshikarya]

for personal understanding: When a primitive data is passed to a method in this case a copy of the primitive data is made and any changes that happen inside the method affect the copy and not the original primitive data due to this we will not see any change in the original primitive data however in terms of object the reference of the object is passed in the method and not the original object itself due to this a copy of the reference is made in the method and not a copy of the object. Now, since the original reference of the object actually pointed to the address of the object, the copy that is made in the method i.e. the copied reference; this reference will also hold the same address in it. Since both references point to the same address, due to this any changes that are made in the copied reference end up affecting the actual object.

[@DK-js8cz]

Method overloading can also be performed by changing the return type of methods, but you have to change the type of parameters also. public class Main { static int plusMethod(int x, int y) { return x + y; } static double plusMethod(double x, double y) { return x + y; } public static void main(String[] args) { int myNum1 = plusMethod(8, 5); double myNum2 = plusMethod(4.3, 6.26); System.out.println("int: " + myNum1); System.out.println("double: " + myNum2); } }

[@sona_772]

[@hiteshahuja633]

At 12:05 it will print " 52 ", because even though the method has changed the copied value but has not returned it to the main function.

[@dnyaneshwarigund9616]

11:46 Output: The value of x after running change is: 98 Reason: Because Here in case of array the reference of array is pass thus it can change the value of arr[0]

[@ikshitgupta1839]

[@AmarjeetKumar-mj9iq]

In simple terms when you create a array with a variable ,the variable get the address of the first index of that array. and when you pass the array the same address is send to method so changes done are permanent and effect the original copy.

11:42 In my opinion Change nhi honi chahiye kyunki marks[0] ki value change2() method k ander change hua hai aur hume print kr rahe hai usse uske method k bahar which is main() method.

Time 11:56 Output The value of X after running change is : 98
