Runtime (Dynamic): Method Overriding (same method signature in parent and child classes). This is driven by Runtime Object Type, not Reference Type.
Allows direct access to static members of a class without qualifying them with the class name (e.g., importing java.lang.Math.* allows calling sqrt() directly). 5. Exception Handling
Achieve encapsulation by declaring class variables as private . A child class provides a specific implementation of
