Understand how subclasses replace inherited methods with specialized implementations. Use @Override annotation.

Explore how superclass references hold subclass objects and how Java resolves method calls at runtime.

Learn when to use abstract classes versus interfaces to define contracts and shared behavior.

Understand base cases, recursive cases, and how to trace recursive calls. Implement factorial, sum, and power.

Apply recursion to string reversal, binary search, and other divide-and-conquer problems.
