Compare block type

So the issue i am having is that i need to check if a the block being placed is a certain block type, however this certain block type is specified in the config file, and its a list of items. How would i check every block type specified in the config file? my code so far:

Code:

if(event.getBlock().getType() != (any one of list of blocks in config)  )
        return false;

@timtower so you just want me to run it multiple times individually?
that seems kinda inneficient... if that is what you are referring too.

 

that wont work because the list is a string and contains() requires an object

 

@timtower
i cant, i am trying to make a factions top plugin, and it will check the factions chunk for this list of items. i am not at that stage yet, right now i am just telling it to return false if it is not one of those blocks so it wont run the event and lag the server more. So whats the second option?
and youi messaged me and said that posting a reply would be against the terms, should i just edit my original post and tag you to reply?

 

LOL. A string is an object?

 

@timtower the issue im having is, is that i dont know how to get materials from a config file.
List<Material> Chck = Arrays.asList(new Material[] {plugin.getConfig().get("Factions Blocks")})
the problem with that is, i cant convert from a string to a material.

 

@timtower do you by any chance have a webpage or tutorial that shows how to convert is by hand? and type().name() returns a banlist
