can someone help me with an NPE? (config)

hello all!
I get an NPE whenever my plugin gets to this line of code:

Code:

            switch(main.instance.getConfig().getString("Players.p"+main.playerHashMap.get(EVNT.getPlayer().getDisplayName())+".team")){

where EVNT is a playerjoin event
and main is the main class
and playerhashmap is a string-key and int value hashmap

my config is as follows:

Players:
--p1:
---- name: tuskiomi
----x: 10
----y: 64
----z: 10
----team: red

 

main, instance or the string you get is returning null. add null checks

 

okay i added some debuggers in my code.

Code:java

            if(main.instance == null){
                main.log.info("main instance is null");//idk, but just in case
            }
            if(EVNT.getPlayer().getDisplayName() == null){
                main.log.info("display name is null");// if the user is herobrine, this will pop up
            }
            if(main.playerHashMap.get(EVNT.getPlayer().getDisplayName()) == 0){
                main.log.info("add 1");//if the hashmap returns 0 tell me to add 1
            }

this was the result

why is my main instance a null and how do i fix it?
