Doubts i stacks

#1

If i have just created a stack using size =5 ,
Will be call that stack as empty??
But isnt it filled with values of zeroes
Also the size of the stack is it determined by “top” , or the size if have entered.
As in this case is the size 0 (top+1) or size is 5??

#2

Also while I was writing code IDE was showing this.data can be final??

#3

How can it be final arent we changing the value of data by pushing or isnt that counted towards “changing” please explain final in more detail

#4

I don’t really understand the thing about final here, but yes, the stack will be called empty if top = - 1 and the size of the stack is technically the number of elements present in the stack at that time.

#5

Can this.data attribute be final while writing our stack???

#6

No, if data is an array it can’t be final because you are changing its contents

#7

But even when i made it final there were no errors?

#8

You must have made the array reference final, which works since you do not assign it to another instance of array

#9

oh ohkay
So i can do final int[] arr;
right?

but how to make an array final so that I cannot change its contents

#10

Honestly, I don’t know how to do that as I have never done it myself.

#11

oh okay
Is it never needed?

#12

no ___________________________
