Solved Error code

Hello,
I'm writing a plugin and want's to test it. Now anywhere is an error.

Error code:

Code:

I never saw such a code before. At those I've seen before, the line stands at the beginning of the code.
Can anyone tell me where my error is? Which class and line is enough.

Thanks!

 

@Ungemonstert The console tells you.
at main.PvPmain.<init>(PvPmain.java:35) ~[?:?]

 

oh. okay. I thought it was right but if it isn't, I would look about it. Thank you @DJSkepter!
