Answer / nc
It is automatic static and final even if you don't declare it.
Why? Because when a class implements these interfaces, these
variables must be able to be accessed by static and
non-static methods. Also as these variables are specific to
any class instances(i.e. at the same time many classes can
implement these interfaces), they must have the same value
across the implementing classes.
Also if you want to load the value of certain values at the
application start up and all implementing classes wants
these values unchanged, then these must be static and final.
So they are static and final.
