Solved How to Update Hologram (no API)

Hi guys,
First sry for my bad english !
Now to my main problem...
I recently code this little method:

Code (Text):

public static void spawnHologram(Location loc, String text, List<Player> players) {
   
          EntityArmorStand as = new EntityArmorStand(((CraftWorld) loc.getWorld() ).getHandle());
   
          as.setCustomName(text);
          as.setCustomNameVisible(true);
          as.setInvisible(true);
          as.setGravity(false);
          as.setLocation(loc.getX(), loc.getY(), loc.getZ(), 0F, 0F);
          PacketPlayOutSpawnEntityLiving packet = new PacketPlayOutSpawnEntityLiving(as);
   
          for(Player p : players) {
             ((CraftPlayer) p).getHandle().playerConnection.sendPacket(packet);
             main.Holograms.put(p, as);
          }
   
    }

but now i have to update the Hologram but don't know how to do that!
It would be nice if someone could help me xD

Edit: The method works fine but i want to change the displayed text after some time

 

Thank you!! It works! For all who are interested in the code:

1st Part:

Code (Text):

public static PacketPlayOutEntityDestroy destroyEntity(Entity entity) {
        return new PacketPlayOutEntityDestroy(entity.getId());
    }

2nd Part:

Code (Text):

public static void spawnHologram(Location loc, String text, List<Player> players) {
       
          EntityArmorStand as = new EntityArmorStand(((CraftWorld) loc.getWorld() ).getHandle());
       
          as.setCustomName(text);
          as.setCustomNameVisible(true);
          as.setInvisible(true);
          as.setGravity(false);
          as.setLocation(loc.getX(), loc.getY(), loc.getZ(), 0F, 0F);
          PacketPlayOutSpawnEntityLiving packet = new PacketPlayOutSpawnEntityLiving(as);
       
          for(Player p : players) {
              if(main.Holograms.containsKey(p)){
                        PacketPlayOutEntityDestroy packet2 = destroyEntity(main.Holograms.get(p));
                        ((CraftPlayer) p).getHandle().playerConnection.sendPacket(packet2);
              }
             ((CraftPlayer) p).getHandle().playerConnection.sendPacket(packet);
             main.Holograms.put(p, as);
          }
       
    }

So its SOLVED!
