[Solved] Identify the error in this code related to polymorphism:class Parent { void show() {} } class Child extends Parent { void show(int x) {} } public class Test { public static void main(String[] args) {... | Java

Java - Polymorphism

Identify the error in this code related to polymorphism:

class Parent { void show() {} } class Child extends Parent { void show(int x) {} } public class Test { public static void main(String[] args) { Parent p = new Child(); p.show(); } }

ACannot assign Child object to Parent reference

BChild class does not override show() method

CParent class method show() is private

DMethod show() in Parent is static

Step-by-Step Solution

Solution:

Step 1: Check method overriding rules
Child class has show(int), which is method overloading, not overriding show() with no parameters.
Step 2: Understand polymorphism call
Parent reference calls show() with no arguments, but Child does not override that method, so Parent's show() runs.
Final Answer:
Child class does not override show() method -> Option B
Quick Check:
Overriding requires same method signature [OK]

Quick Trick: Overriding needs exact method signature match [OK]

Common Mistakes:

Confusing overloading with overriding
Thinking polymorphism works with overloaded methods
Assuming assignment causes error
