Integer returning null only after saving in an object.

Hello, I am having trouble returning the value of an integer after I save it in an object. I am creating the object in my onEnable and the value does return correctly before I save it to my object, but the value returns null after trying to obtain it from the object. Thank you everyone for your help! Here is my code:

You are not assigning a value to the variable, so it returns null

 

@MrGeneralQ Ok, thank you for trying to help me out, but I'm a little rusty on this stuff, could you possibly help me out to how I should go about assigning the value to the variable?

 

@The_Roycester
You're also not assigning a value to the plugin variable in your main
just do
private static Plugin plugin = this;
private static methods m = this;
also you should try to avoid using static, use constructors to access other classes

 

@Blackwing_Forged thanks for your reply I am going to try what you said I’ll let you know if it worked.
