Null check in an enhanced for loop

Question

What is the best way to guard against null in a for loop in Java?

This seems ugly :

if (someList != null) {
    for (Object object : someList) {

For anyone uninterested in writing their own static null safety method you can use: commons-lang's org.apache.commons.lang.ObjectUtils.defaultIfNull(Object, Object). For example:

    for (final String item : 
    (List)ObjectUtils.defaultIfNull(items, Collections.emptyList())) { ... }
