I'm not a C# coder but I understood it was possible to have non-nullable types?

Keep meaning to try C# for a project sometime. I understand it to be a more expressive, programmer friendly Java.

Value types are non-nullable. But they're also stack-allocated* and passed by value, so they're really only appropriate in certain cases. You can't use them as general-purpose non-nullable objects.

*In practice, though technically that bit's an implementation detail of Microsoft's run-time and not part of the language spec.

For some data types. Strings and objects can always be nullable.
