Your question is Core Pillars of OOP. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe the core pillars of object-oriented programming: polymorphism, inheritance, abstraction, and encapsulation.
Explain what each pillar means, how the mechanisms work in Java, and give a concrete example showing how they relate. Distinguish compile-time type checking from runtime method dispatch and identify common misuse of inheritance.
Scope: Use Java terminology and object-oriented design principles; no implementation beyond a short illustrative example is required.
