Thank you for concisely explaining these concepts that were difficult for me to grasp. I passed my Intro to Programming because of you :)

Java always performs pass by value in case of objects it creates the copy of the reference.

fantastic, no need to check any other video now.

You are really good at concepts. i wish i learn enough to explain others the way u did. Thank u for this tutorial. It helped me a lot. God Bless. :)

[HellaPointsBro]

lol took me until your video to finally understand this concept thank you :)

[hello-mpkz]

Thank you so much sir for helping me to understand 😊😊
Please make videos on recursion functions and how to do programs based on recursion 😭😭😭
Plzz 🙏🙏🙏

Very well explained tutorial. Now i am clear with this weird concept of pass by value and bla bla

Sir, you have explained it in the best way I ever saw on any YouTube channel. Thank you. Hope this helps me in my exams

Great Explanation, I just wanted to add that Strings also get passed by value just like integers and are not mutable like the array[0].

You are using two variables called value.  When you invoke the 2nd occurrence of the variable called value (when value is passed as a method parameter), does that result in the creation of a second block of space in the physical memory, or is there only one physical space in memory when you use the second occurrence of the variable called value since both variables share the same name?

you are a great teacher, watched so many videos, nobody explained it like you! thanks

[techboi]

Thanks, you finally made this make sense to me :)!!

[saurabhpathare]

Thank you so much. You are a blessing in disguise.

If i understand, we pass only copy of value of reference, not reference? If that true, in Java is more precisely said, that can pass only by value(value of primitive types, and value of name of reference types). Am i wrong?

[hgfggjjgv]

What about strings, it's also reference type.. it's not getting changed if i pass it to another method. Is it because of immutability?

Hi Bro, Sorry that I don't know your name (hence no reference to name), but your explanation was spot on! It helped me to gain clarity on this concept and I am really grateful to you for that! Your explanations are really good, and to the point! Even better than the one in Oracle's Java Documentation! Thanks man!

[asawarisutar]

Crisp. It did clear doubts! Thank you!

How about variables declared inside methods? If we create an object o1 and then pass it to a method and inside the method we create another object o2 and do o1=o2 How does java deal with this ?
