How do I reduce lag with my OnJoin class?

My OnJoin class is clearly causing lag, because 65% of the time, when I join the server, it keeps me imobilized and does scoreboard flashing. Then, it teleports me, after like 5-30+ seconds.

Now, what section of the code might be causing the most lag? And how should I make the code more efficient and less laggy?

 

@Agentleader1 Well, I can tell you one thing. All of it is causing the lag. Maybe try seperating different things like scoreboard, into different classes?

 

What's with all your tries and catches? They are completely redundant.

 

Oh my dear god

 

So why do you.. wait what..

/thread

 

@jthort @Protophite @Monkey_Swag @CodePlaysMinecraft

You guys don't understand the code. I just need ways to reduce lag ;P

Also, I'm converting from CONFIG, to DATABASE

 

@Agentleader1 http://www.oracle.com/technetwork/java/codeconventions-135099.html

 

I don't think you understand your own code

 

@Agentleader1

You write it again, from the ground up. Without all the redundant code, logic errors, public static members, and actually use OOP principles.

How about you write some working code before you make it even more spaghetti, yea?

 

@Agentleader1
I understand what you are trying to do, but you are right. I don't understand your code, beceause its beyond bad.
