    Just to elaborate. . .

    Java has a strict distinction between primitive types and non-primitive
    types. You cannot create new primitive types, and you cannot cast a
    primitive type to an object reference.

    In .NET the type system containes both value types (which perform like
    primitive types, are passed on the stack and have value semantics) and
    reference types, which perform like Java Objects.

    In doing this, .NET gets better performance for things like Decimal and
    database-specific types which can be implemented as value types, and
    eliminates the annoying manual boxing in Java where each primitive type has
    an object wrapper type.
