Variable Value Modifier Description
null The access is forbidden. Used in the getKeyword place, it means that
the variable is accessible just for writing; using it in the setKeyword
renders the variable read-only. Even if no errors are reported, having
null in both positions makes no sense.
default The variable is treated as a conventional variable. Declaring it with
default in both getKeyword and setKeyword positions, is exactly the
same as having an instance variable, but can enforce the semantic that
the access modifier may need to be changed in the future.
