Java - Polymorphism

Which of the following statements about method overriding in Java is correct?

AStatic methods can be overridden

BOverriding methods must have the same or narrower access modifier

COverriding methods can throw new checked exceptions not declared in the parent method

DReturn type of overriding method can be a subtype of the original method's return type

Step-by-Step Solution

Solution:

Step 1: Review exception rules in overriding
Overriding methods cannot throw new or broader checked exceptions.
Step 2: Review access modifier rules
Overriding method must have same or wider (not narrower) access.
Step 3: Review return type and static method rules
Return type can be subtype (covariant). Static methods cannot be overridden, only hidden.
Final Answer:
Return type of overriding method can be a subtype of the original method's return type -> Option D
Quick Check:
Covariant return types allowed in overriding = A [OK]

Quick Trick: Overriding allows covariant return types, not new checked exceptions [OK]
