CallByVal And CallByRef -studied online but coudn't understand . After seeing your video cleared by doubts . Thanks Naveen . great info

[jinalshah]

So wonderfully Explained Sir..Thank you 👍

[nageshbakre]

Very well explained sir... Thank you !!

[Sreelekshmii]

Java does manipulate objects by reference, and all object variables are references. However, Java doesn't pass method arguments by reference; it passes them by value.

[Ajit-kdoi]

Hi Naveen, Excellent work and explanation. Thank you so much for your time and effort ... All the core Java concepts you've cleared so far in the best way possible. Thanks again..

[rohinikannan]

Hello Naveen, thank you so much for the efforts that u have in teaching us, I feel u r teaching better than institute,

[अनंतB]

hi Naveen, can you please share an example in an application where call be reference is being used.

[madhurinaidu]

Hi Naveen
Ur teaching makes subject simple thanks for ur efforts
Can you give and example where do we use callby value and call by ref in Selenium..
Thanks in advance

Hi Naveen,
I can swap two number with following :
package ClassPackage;

public class Callbyreference {
int p;
int q;


public static void main(String[] args) {
// TODO Auto-generated method stub
Callbyreference obj = new Callbyreference();

obj.p = 50;
obj.q = 60;
obj.swap();
System.out.println(obj.p);
System.out.println(obj.q);



}
public void swap() {
int temp;
temp = p;
p = q;
q = temp;
}
Then what is the use of class variable in method public void swap(Callerreference t) and why do we pass obj in called method i.e. obj.swap(obj)? as swap is possible without using class variable

[shivalingneralagi]

Very nice and simple explanation. Easy to remember and apply. Thank you very much for sharing your knowledge.

[amitasn]

Hi Naveen. Could you please tell me what is the name of application you're using to create diagrams in mac

[sehbdusa]

Where do we use this concept in selenium, please follow up

[sameulsmock]

Naveen some of the videos showing that java doesn’t support call reference. But you are saying it is possible. Please clarify me which is correct?

[JayKumar]

Hi Naveen, Thanks for such knowledge full videos but I have a query on CallByRef, as you have shown that this is possible with Global variable. So can you also let me know how to do CallByRef using function/local variables?

[umeshchandra]

What is the default behavior of Java, is it Call by Value or Call by Reference?

[ramakrishnants]

instead of t, if i use obj itself, it still works. am i doing it right?

[thiery]

Oooh, that means if you call by reference, that means you put the whole object into a method; then inside the method, you can manipulate the variables inside the object.
Kind of paradox. Like a chameleon, where the object keep on changing clothes.

[shikhaverma]

Hi naveen i am getting error as " obj cannot be resolved or is not a field"
Could you please suggest how to fix it.
