What is the effect of calling a dynamically bound method within a constructor in Java?

  1. Does not compile

  2. Runs without issue

  3. May operate on uninitialized members

  4. Throws an exception at runtime

The correct answer is: May operate on uninitialized members

If a dynamically bound method is called within a constructor in Java, the method may operate on uninitialized members of the object. This is due to the nature of dynamic binding, which occurs at runtime and can result in a method being called before the object is fully initialized. Option A is incorrect because the code will compile without any errors. Option B is incorrect because although the code may run without any issues, the method may still operate on uninitialized members. Option D is also incorrect because the code will compile and the exception will only occur at runtime if the method tries to access uninitialized members.
