Which option is better Boolean or Enum as method parameters [closed]

I have a method method update(Student std, Boolean isupdateRequired) On the basis of isupdateRequired flag i am updating the value of Student Object.

Now it's simple and i am not marking any columns value as true/false by using isupdateRequired.

Now my questions is that for above mentioned case is Enum is better option instead of Boolean? If yes why to use Enum.
