Hello,
I'm curious why VB.NET uses the Overrides, Overridable, NotOverridable, and MustOverride keywords to specify how methods and properties might or might not be overridden.

In Java, it is not necessary to use those keywords to override a class.
To me, Java way is simpler and clear to read codes.
So Overrides, Overridable, NotOverridable, and MustOverride keywords are unnecessary in my mind.

Any thoughts?
