Multiple choiceHardchapter-5-curatedpremiumooppolymorphism
class Order { String getOrderDetails() { return "Order details from Order"; } }
class SpecialOrder extends Order { String getOrderDetails() { return "Order details from SpecialOrder"; } }Answer and explanation
Correct answer
A. Order details from SpecialOrder
Why
Despite 'Order' having its own 'getOrderDetails' method, the 'SpecialOrder' class overrides it. Hence, the overridden method in 'SpecialOrder' is executed, demonstrating polymorphism at runtime.
