Difficulty: Easy
Correct Answer: The code executes with no output.
Explanation:
Introduction / Context:
This checks whether you can distinguish a true Java constructor from a method that merely shares the class name. A constructor has no return type, not even void. If a return type is present, the member is a regular method and will not be invoked by object creation unless called explicitly.
Given Data / Assumptions:
Concept / Approach:
Because void A() has a return type, it is not a constructor. The compiler synthesizes a default no-argument constructor A() that does nothing. Therefore, new A() calls this implicit constructor, not the method, resulting in no output.
Step-by-Step Solution:
Verification / Alternative check:
Remove the return type: change "void A()" to "A()". Then new A() would print "Class A".
Why Other Options Are Wrong:
Common Pitfalls:
Assuming any member with the class name is a constructor; forgetting that a return type disqualifies it as such.
Final Answer:
The code executes with no output.
