1.14.4 Get all Slabs Types

Hey! I'm trying to get all the slabs type to add the value of the block place statistic of every slab. Do yo know if there is any way to get all slabs automatically without adding it manually? There are a lot.

I found this thread but it's to old, I don't know if it works. https://www.spigotmc.org/threads/half-slabs.199209/

Ty!

 

Thank you!
So... this code should work? Because is not working

Code (Java):

    public void getSlabs(Player p) {
        for(Material m : SLABS.getValues()) {
            p.sendMessage(m.name());
        }
    }
