Java - Polymorphism

Which syntax correctly shows method overriding for runtime polymorphism in Java?

Aclass Parent { void show() {} } class Child extends Parent { void show() {} }

Bclass Parent { void show() {} } class Child extends Parent { void display() {} }

Cclass Parent { void show() {} } class Child { void show() {} }

Dclass Parent { void show() {} } class Child extends Parent { void show(int x) {} }

Step-by-Step Solution

Solution:

Step 1: Check method overriding rules
Method overriding requires same method name and parameters in subclass extending superclass.
Step 2: Match options with overriding
class Parent { void show() {} } class Child extends Parent { void show() {} } shows subclass overriding show() method correctly; others differ in method name or parameters.
Final Answer:
class Parent { void show() {} } class Child extends Parent { void show() {} } -> Option A
Quick Check:
Same method name and parameters in subclass = overriding [OK]

Quick Trick: Overriding needs same method name and parameters in subclass [OK]
