Solved UltraHardcore

Hi, so I am very new to the whole Java thing, and I decided to work on a plugin. I watched a video on youtube which made Zombies wear diamond armour, and Creepers always charged. From there, I extended it to include other mobs. It got to the point where I decided to test it on my server, but it failed to actually do something. I was hoping someone could look over my code, and see what I did wrong that made it not work. Codes below:

Code:

    }
}

Apologise in advanced if I just messed it up.

 

Thank you, I got it working
