#7.6 Kotlin Functions: Named Parameters Video Lecture | Kotlin Tutorial for Beginners: Learn Kotlin in easy language - Back-End Programming

let us now proceed and check out one
more concept in this section of
functions such as named parameters
now this named parameter is a pure core
clean functionality it is not actually
present in Java so there is no chance of
interoperability in this case of named
parameters so inside the IntelliJ IDE
this is the same project on top of which
we were recording in the previous videos
so here inside the finite volume method
I will simply modify my code and now
here I will simply remove the return
type from here and also remove the
return type from here and then simply
modify my code inside the main activity
as well
sorry main method as well and now
suppose if I run the code right now
let's see what happens and now inside my
Java file we have some error so let us
commend these two lines of code because
we don't need it in this video so inside
the Cortlandt file let us now click on
this icon and then run the code so in
the output we get length is 2 breadth is
3 and height is 30 and now suppose if I
use the naming parameter such as if I
use length equal to 2 breadth equal to 3
and height equal to 30
so here the sequence is exactly same as
the formal arguments that we have
defined here right so here length equal
to 2 will fall here bread equal to 3
will fall here and height equal to 30
will fall here now what if I change the
sequence
suppose if I cut the height 30 from here
come on text and paste it right at the
beginning and then let's check out what
happens when we execute our code so
simply run the code so here in the
output console the output remains same
length is again to breadth is 3 height
is 30 now what the heck is happening
here now this is the beauty of the
naming parameters in case of Cortland
here we have defined height equal to 30
so no matter what is the sequence of
these pair
meters right here inside the main method
this height equal to 30 will match with
this height equal to 10 and override it
similarly the length 2 will fall here
and the breadth 3 will fall here right
and now suppose if I remove the height
from here and then we are only left with
the length and breadth so this length
will come here and width will come here
as we all are aware of it and the height
will get its default value now again
let's change the sequence command X and
paste it here and now make a note here
we are only having two parameters and
here we have three parameters now in
spite of changing the sequence and also
reducing the number of parameters the
breadth will fall in its own path that
is this one and the length value will
come here
right let us now run the code so here we
go again the length is 2 bit is 3 and
height is 10 now the advantage of using
the naming parameters in case of
cortland is that if suppose you have
seven to eight parameters inside this
method so in that case it will simply
give you a safer side of defining the
actual arguments inside the main method
so this will simply help you to avoid
any mistake by defining the values right
here so hope you got something out of
this video thank you and have a good day
