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.

[mellow epoch]

as said before this method does not work for primitives

[jade remnant]

then which one works?

is there any predefined method for descending sort?

[molten plank]

afaik the only way is to box into reference types ie Integer[]

[jade remnant]

what

[molten plank]

use Integer[] instead of int[]

[mellow epoch]

https://www.baeldung.com/java-sorting-arrays#descending-order
thats how baeldung is managing that

but there are many ways to turn the ints to Integer

[jade remnant]

Which one do I replace Integer[] with? the colour code is changing to blue

its changing as variable name

[molten plank]

yea but none of the ways are good...

[mellow epoch]

yeah...

[molten plank]

change int[] a to Integer[] a

and also

it's int[] a, not int a[] now that I see it, the second one is a legacy from C that shouldn't be used

[jade remnant]

lol it worked

whats the difference between int and integer?

[molten plank]

first is a primitive type, second is a reference type, or object if you prefer

it's a bit complex

[jade remnant]

my habit from C/C++

[jade remnant]

java complex af

[molten plank]

but to put simply, Collections.reverseOrder() is using something called generics, and generics are not supported by primitives

[molten plank]

complex for someone who doesn't know java*

well, I guess it's complex anyway 🤔

[molten plank]

and for whatever reason, they didn't add a method specifically to sort ints with custom order, so you have to use this inferior solution...

[mellow epoch]

btw are they going to revamp/add some methods when this new generic update comes?

forgot the name

value types or smth

idk

[molten plank]

they won't need since int will now work with generics

[molten plank]

valhalla ?

[mellow epoch]

ah ok

but will they remove the primitive specific methods then?

[molten plank]

no

[mellow epoch]

yeah, backwards compatibility prob

[molten plank]

why would they remove them ?

[mellow epoch]

was just stupid

mb
