propose nullToZero(Integer) method for Ints

[GoogleCodeExporter]

public static int nullToZero(Integer input)
{
   return input == null ? 0 : input.intValue();
}

and probably same for other similar helper classes (Floats, Doubles, Longs, 
etc.)

Some Thoughts/Possible Alternatives:
 - In each primitive class have a defaultIfNull(T value, T default), maybe with defaultIfNull(T value) delegating to the 2 param. version with a suitable default (ex 0 for numeric primitives)
 - Functions<T, T> defaultIfNullFunction(T value, T default) in Functions

Or...

Objects.firstNotNull(input, 0).intValue();

I was just trying to stick to the naming convention used for Strings.nullToEmpty

I'd use Jim's suggestion.

int value = (int) Objects.firstNonNull(input, 0);

Thanks for that.

Also, I have something like the following:

y = z == null ? "" : z.getX();

I know this one is a bit tricky, but is there any helper method for this kind 
of thing?
