While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

fringe plume how do i cast a supplier Supplier<Class> -> Supplier<SuperClass>

why

fringe plume Dec 21, 2022, 5:57 PM

#

because i have to

#

it takes in a Supplier<Super>

#

and i extend Super so i can add some custom things to it

lapis osprey Dec 21, 2022, 5:58 PM

#

explain your problem please

#

that's a xy question

fringe plume Dec 21, 2022, 5:58 PM

#

not really

#

i can give an example but

#

i have an Supplier<Inventory>

#

the method takes in an Supplier<Container>

#

Inventory implements Container

#

if i use .get and then a supplier than it defeats the whole purppose of the supplier

lapis osprey Dec 21, 2022, 6:00 PM

#

why do you have a supplier<inventory> at the first place

fringe plume Dec 21, 2022, 6:00 PM

#

i guess i can add another parameter

#

but now i have

#

which is ugly

#

thought i could maybe do it cleaner

lapis osprey Dec 21, 2022, 6:02 PM

#

what's the problem ?

#

why is it ugly ?

#

idk seems dumb passing in the same thing twice

#

fringe plume idk seems dumb passing in the same thing twice

then store it in a variable ?

fringe plume Dec 21, 2022, 6:03 PM

#

eh this works fine i guess

sullen sinew Dec 21, 2022, 6:09 PM

#

or refactor the method, if its the same input anyway ...

fringe plume Dec 21, 2022, 6:25 PM

#

well i cant is the thing

#

one gets cast and one doesnt

sullen sinew Dec 21, 2022, 7:33 PM

#

shouldnt stop u from only using one in the signature

fringe plume Dec 21, 2022, 7:59 PM

#

Well it did pepekek

#

That’s why I asked how to cast it

#

Can you show the method that's being called?

slim geode Dec 22, 2022, 2:31 AM

#

@fringe plume In your argument list take a Supplier<? extends SuperClass>

#

then you don't need to cast
