Identify the misconception in the following statement: "Method overloading allows a subclass to provide a new implementation for a method with the same signature as in the superclass."
Identify the misconception in the following statement: "Method overloading allows a subclass to provide a new implementation for a method with the same signature as in the superclass."
AOverloading and overriding are interchangeable terms describing the same concept.
BOverloading requires different parameter lists, so same signature means overriding, not overloading.
COverloading is resolved at runtime, so subclass implementations override superclass methods dynamically.
DOverloading can only occur within the same class, not across superclass and subclass.
Step-by-Step Solution
Solution:
Step 1: Define method signature and overloading
Method signature includes method name and parameter types; overloading requires different signatures.
Step 2: Analyze statement
Providing a new implementation with the same signature in subclass is overriding, not overloading.
Step 3: Evaluate options
A is incorrect; overloading and overriding are distinct concepts. B is true but not the main misconception. C is false; overloading is compile-time. D correctly identifies that same signature means overriding, not overloading.
Final Answer:
Overloading requires different parameter lists, so same signature means overriding, not overloading -> Option B
Quick Check:
Same signature means overriding, not overloading [OK]
Quick Trick:Overloading needs different parameters; same signature is overriding [OK]
Common Mistakes:
MISTAKES
Confusing overloading with overriding
Thinking overloading applies across classes
Believing overloading is runtime
Trap Explanation:
PITFALL
Candidates often misuse 'overloading' to describe overriding due to signature confusion.
