Clearly saySomething comes from super class. This is confusing for

The method-resolution mechanism moves up the inheritance hierarchy from the compile-time type to look for the first matching method at runtime. Since CowTest "is-an" AnimalTest, the invocation from CowTest can find the method in AnimalTest.

However, if CowTest did have a matching static method, it wouldn't override the superclass static method, it would hide the superclass static method. There is no polymorphism of static methods.

AnimalTest.saySomething() will never invoke CowTest.saySomething().
