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) {
            


        

Answer 1

Use, CollectionUtils.isEmpty(Collection coll) method which is Null-safe check if the specified collection is empty.

for this import org.apache.commons.collections.CollectionUtils.

Maven dependency

    org.apache.commons
    commons-collections4
