Avoiding null checks in java

I have the following code :
if (task.getCompletor() != null) {

The getCompletor returns a User -  :
public WorkflowUser getCompletor() {
        return completor;

what are the ways i could avoid the null check.
One way i can think of to user a NullWorkflowUser class so instead of directly returning the completor from the getter i return this object in case its null this way i dont have to have a null check and i could write the definitions which will be null for the methods inside it.
I have read about Optionals but never used it.
Can that be used here.
Which is a better approach the NullWorkflowUser or the Optional one.

And any other alternatives in java.
