What's wrong with overridable method calls in constructors?
....out.println(x);
}
}
new Child(42); // prints "0"
}
}
Here, when Base constructor calls overrideMe, Child has not finished initializing the final int x, and the method gets the wrong value. This will almost certainly lead to bugs and errors.

How to convert C# nullable int to int
...if(v1==null)
v2 = default(int);
else
v2 = v1;
Also, as of .NET 4.0, Nullable<T> has a "GetValueOrDefault()" method, which is a null-safe getter that basically performs the null-coalescing shown above, so this works too:
v2 = v1.GetValueOrDefault();
