Thanks Nick , I got the point . Actually I was thinking that every array is implicitly sub class of Arrays class . But this is not the case , primitives array extends from Object class ( as every other class extends ) & reference variable array extends from Object class & that extends Object class . And Arrays class provides static methods for manuprlatings this arrays .
