Java - Constructors

Identify the error in this code snippet:

class Parent {
  Parent(int x) {}
}
class Child extends Parent {
  Child() {}
}

ANo error, code compiles fine

BParent constructor must be no-argument

CChild class cannot extend Parent with parameterized constructor

DChild constructor must call Parent constructor explicitly

Step-by-Step Solution

Solution:

Step 1: Check Parent constructor
Parent has only a parameterized constructor, no default constructor.
Step 2: Check Child constructor
Child's constructor does not call super(int), so compiler error occurs because no default super() exists.
Final Answer:
Child constructor must call Parent constructor explicitly -> Option D
Quick Check:
Missing explicit super call = error [OK]

Quick Trick: If parent has no default constructor, child must call super(params) [OK]
