Java Programming Tutorial - 73 - Moving List Items Program Video Lecture

what is going on guys welcome to 73rd
Java tutorial and in this tutorial we're
going to be finishing up our program and
actually running it so in the last story
we created a list on the Left we created
the move button we added some
functionality to it so now we go ahead
and only thing we have to do is create
the list on the right so let's go ahead
and make right list and just go ahead
and like set it equal to nu J list and
we don't need any parameters for it
because by default we want nothing in it
so that's why I don't need any
parameters for it right now you can if
you want but I mean it'll be kind of
useful and hold on let me H my ear feels
good right in there Oh disgusting so now
what we need to do is since we have
nothing in our list by default then it's
not even gonna appear on the screen by
default since I mean it doesn't have
anything in it so what we need to do is
set a default height and width for it
pretty much so let's go ahead and see
what are we put up here for 3 ok what we
need to do is first take that write list
and to make sure it appears on the
screen by default what we need to do
first is get out of my way
set visible row count and I'm gonna set
this equal to 3 because our other one is
set to 3 n I just want some consistency
so next I'm gonna take that write list
and we need to set fixed cell height and
width so set fixed so let's do with
first I mean only makes sense it will
set a width of like a hundred and do the
same thing for height right list set
fixed
crap my default thing height and we'll
set this equal to like 15 or something
like that
and this should be enough to hold her
values if it's not we'll go back and
tweak a little bit but oh well and the
last thing we have to do aside from this
is take that right list and we need to
set the selection mode like before it so
set selection probably can copy this
from up there but too lazy to set the
selection mode make sure to enter right
get selection mode and what this is into
list selection model dot and we're gonna
write Wow how convenient is that
multiple interval selection so then once
I type a write list and type this right
what this is going to do is allow you to
select the multiple items from the
right-hand side and I know you guys
can't see that multiple interval
selection so just like that now that we
have our right list made the only thing
we need to do is add it to the screen so
let's go ahead and add new j scroll pane
so we want a scroll ball urn this one to
write list so now we have everything
added to our screen and our program is
basically built right here so let's go
ahead and in our main I already have
this stuff from the last Oriels let's go
ahead and run this and see what we got
well I resize my window a little weird
but we can always change that by setting
the size right here but I'm too lazy for
now so as you can see the title is
tighter title and now unlike before
where we can select single things if I
hold down the shift key on my keyboard
look at this click and now I get a
multiple selection or if I hold down
ctrl on my keyboard I get that selection
where you can select like every other
one or if you want to deselect something
just click it again and now if you move
it you get bacon more bacon or if we
want bacon
in ham I'm going to click bacon hold
down shift click ham and move and we get
bacon wings in ham and of course
following everything let's go ahead and
just select that move and now we got
everything right there so that is pretty
much the program of using a multiple
interval selection or or in other words
multiple selection lists and one quick
time how this program works we've pretty
much made variables right here in an
array we took that array and passed it
into left list so left list will have
something to display we set the visible
row count we made it so you can select
multiple things and we also made a
scroll bar on the left list then we got
to the move button we did all this
default stuff on he also did this cool
stuff setlist data of the right list
automatically depending on what you
select in the left list that's why
whenever we create click move it first
looked what we selected in the left list
and depending on what we selected that's
what I put in the right list so this is
how you do that using setlist data in
the get selected values method we added
that button to the screen and then what
we did is we made a new write list that
was empty by default and since it was
empty by default it wouldn't display if
we didn't give it a height in width and
now we made that list so you could
select multiple things in it even though
you didn't really need to and last but
not least we added the right to the
screen so everything was added to the
screen and it was good to go
and it was good to run so that is our
final program using multiple selection
lists I hope you guys enjoyed it I got
the hiccups now so thank you guys for
watching don't forget to subscribe and I
will see you next tutorial
