Title: Key Concept - Super Keyword
Course: CPS 189: Java Certification - Review, Practice & Prepare (Development) > Section: Learning Modules

- The super keyword is used in a subclass to:
  - Call a superclass constructor.
  - Call a method in the superclass.
  - Reference a hidden field in the superclass.

- If a subclass constructor does not explicitly call a superclass constructor, Java automatically calls the (no-argument) constructor of the superclass. A compile-time error will result if the superclass does not have a no-argument constructor.
