Help Auto equip

Hello cheaters, Well, I'm implementing my Capture the Flag (CTF) event, I want to put it on when a player picks up a flag and delivers the weapon he was equipped to return without needing to do it himself.

can you give me examples how can i do this? because I tried creating an array but it didn't work

if (_flags.keySet().contains(npc))
		{
			if (getState() != EventState.RUNNING)
				return true;
			
			if (_flags.get(npc) == getTeam(player) && _flagWielders.values().contains(player))
			{
				player.destroyItemByItemId("Event flag.", 6718, 1, null, false);
				player.broadcastUserInfo();
				announce(player.getName()+" has scored for "+_flags.get(npc).getName()+"!", false);
				
				increaseScore(player, 1);
				
				for (Npc flag : _flagWielders.keySet())
				{
					if (_flagWielders.get(flag) == player)
					{
						_removeFlags = flag;
						break;
					}
				}
				
				_flagWielders.remove(_removeFlags);
				return true;
			}
			
			if (_flags.get(npc) != getTeam(player) && !_flagWielders.keySet().contains(npc))
			{
				ItemInstance flag = player.addItem("Event flag.", 6718, 1, null, false);
				player.useEquippableItem(flag, true);
				player.broadcastUserInfo();
				announce(player.getName()+" has got the "+_flags.get(npc).getName()+" flag!", false);
				player.broadcastPacket(new SocialAction(player, 16));
				_flagWielders.put(npc, player);
				return true;
			}
		}
