A subclass can use its superclass constructor to set values for the fields it inherits from the superclass by calling the superclass constructor using the keyword "super". This will then pass any arguments from the subclass constructor to the superclass constructor, which will initialize the inherited fields with these values. The subclass constructor can optionally also define any additional field values specific to the subclass. This approach ensures that the inherited fields are properly initialized and avoids the duplication of code for initializing these fields in both the superclass and subclass constructors.
