Development Assistance Getting Item Drop Amount NMS (Block Break Event)

Code:

for (ItemStack i : e.getBlock().getDrops()){
            if (p.getInventory().firstEmpty() == -1){
                p.sendMessage(F.main("Prison", "Your inventory is full!"));
                e.setCancelled(true);
                return;
            }
            net.minecraft.server.v1_8_R1.Block nmsBlock = net.minecraft.server.v1_8_R1.Block.getById(??????);
            net.minecraft.server.v1_8_R1.World world = (net.minecraft.server.v1_8_R1.World) e.getBlock().getWorld();
            int dropCount = nmsBlock.getDropCount(1,world.random);
            i.setAmount(dropCount);
            p.getInventory().addItem(i);
        }

My code is above, I also tried e.getBlock().getDrops(p.getItemInHand())); But that does not work either.
I have no idea how to get the block, or if the int dropCount will work to get the drop amount of that item.
