Setting attributes to null using a config file set by the user

I am working on a project where I was asked to make it so that the user can enter attributes that they want obscured from a .yml config file. The attribute already has a value in it and it will be set to null based on whether the user wants that attribute obscured.

For example if the variable String country = "Canada"; exists and the user specifies "country" in the config file, country will be set to null.

The class has get and set methods. But I don't really understand how I can set the attributes to null.

For example, I'd have to set the value to null like Object.setCountry=null; but I won't know what set method to use Object.xxxx=null;
