  • Inheritance established “is a” relationship between classes.

    class Turtle;  
    class TigerTurtle is a Turtle (but better);  
    class BossTurtle is a Turtle (but better);  
    

    Underlying classes hold an inner object to the super class, everything from Turtle will be in TigerTurtle and BossTurtle.

    In some languages that is configurable with public, private, protected keywords.

    Relatedly, there’s also composition, which establishes a “has a” relationship:

    class TurtleTail;
    class Turtle:
      var tail: TurtleTail; (has a tail);
    

    Since Turtle is NOT a tail, but a whole animal, turtle should not inherit TurtleTail. But it HAS a tail, thus we add turtle tail as a property.



  • Generally, it is not advisable or legal to take a duck home from a park. Many parks have rules and regulations designed to protect wildlife, and removing animals from their natural habitat can harm both the animal and the ecosystem. If you find a duck that appears to be injured or in distress, it's best to contact a local wildlife rehabilitation center or animal control for assistance.
