Need help changing stuff inside the .class files.

Hi, so i'm using a java decompiler and I want to edit this .class (its a plugin and it gives a diamond sword unbreaking, sharpness, fire aspect, knockback on VII (7) I want to edit it so it adds smite 7 but i'm not sure how. If someone who knows how to do this can reply i might just post a screen shot.

Edit : Using eclipse and still don't know what to do

Look at how other enchantments are added.Profit.

Yea I looked but I dont know what smite is....
