Utility to check null and return size as 0 if empty for a collection/list in java

Question

I have list which can be null sometimes, the return type should be int ex:

int size = 0; 
if(list != null) {
    size = list.size;
} 

Could you please let me know whether any utility is available?

Thanks.

Answer 1

What about

int size = (list == null) ? 0 : list.size();

I'm not sure why you would want a utility for this, since the above seems simple enough.
