Why is “null” present in C# and Java?

Question

We noticed that lots of bugs in our software developed in C# (or Java) cause a NullReferenceException.

Is there a reason why \"null\" has even been included in the l

Answer 1

Nullity is a natural consequence of reference types. If you have a reference, it has to refer to some object - or be null. If you were to prohibit nullity, you would always have to make sure that every variable was initialized with some non-null expression - and even then you'd have issues if variables were read during the initialization phase.

How would you propose removing the concept of nullity?
