auto populate contact's field value on case's fields before saving the record

I have contact name field on case, requirement is fields related to contact (i.e.first Name, last name, email, phone etc.) should autopopulate before saving the record.

You can able to do it using process builder or workflow or apex trigger 



You can use a workflow rule for this functionality. Create a workflow with the field update as the workflow action. As Contact is a lookup on the case object, you can reference Contact  object's field in the field update using the formula editor in the field update screen.
