Checking values on a list. Please Help.

Okay, so I am working on the skelton of a grief prevention plugin for my server, and I have the plugin sucessfully logging block place events and block break events with a specialized ID of the form <UUIDofPlayer>:<Block>:<x>:<y>:<z> and i am trying to create a 'for' loop that finds if there has been a block place where a player tries to break a block and deny it if their was. Here is the loop:

if(meguy26basic.plugin.getConfig().getList("BlockPlaces").contains(BlockPlaceID)) {
}
else {
List<String> list = (List<String>) meguy26basic.plugin.getConfig().getList("BlockPlaces");
for (int i = 0; i < list.size(); i++) {
String element = list.get(i);
String delims2 = ":";
String[] IDS2 = element.split(delims2);
if(IDS2[2] + IDS2[3] + IDS2[4] == IDS[2] + IDS[3] + IDS[4]){
Bukkit.broadcastMessage("DENY!");
onBlockBreakUngrief.setCancelled(true);
break;
}

}
}

the event priority is set to highest and the"DENY" does not broadcast....

 

Use .equals() to compare Object values, not ==. Use == for primitives and null checks.

 

Thanks.
