[Solved] Find the error in the following code snippet:class Parent { final void show() { System.out.println("Parent show"); } } class Child extends Parent { void show() { System.out.println("Child show"); } } | Java

Java - Inheritance

Find the error in the following code snippet:

class Parent {
    final void show() {
        System.out.println("Parent show");
    }
}

class Child extends Parent {
    void show() {
        System.out.println("Child show");
    }
}

AParent class cannot have final methods

BChild class must declare show() as final

CChild class cannot override final method show()

DNo error, code is valid

Step-by-Step Solution

Solution:

Step 1: Understand final method behavior
Methods declared final in a parent class cannot be overridden in child classes.
Step 2: Analyze Child class method
Child class tries to override final method show(), which causes a compile-time error.
Final Answer:
Child class cannot override final method show() -> Option C
Quick Check:
final methods block overriding [OK]

Quick Trick: final methods cannot be overridden in subclasses [OK]

Common Mistakes:

Thinking final methods can be overridden
Assuming no error in overriding final methods
Confusing final methods with abstract methods
