Mastering Java: The Ultimate Quiz for 'Thinking in Java'

Can constructor in Java be overridden?

1. Yes

2. No

3. Only if it is a default constructor

4. Only in a subclass

The correct answer is: No

In Java, constructors cannot be overridden. This is because unlike methods, constructors cannot be inherited by subclasses. This means that a subclass cannot override the constructor of its superclass. However, a subclass can specify which constructor of the superclass should be invoked when creating an instance of the subclass. Option A is incorrect because constructors cannot be overridden, but can be invoked through the use of the super keyword. Option C is incorrect because the type of a constructor (default or non-default) does not affect its ability to be overridden. Option D is incorrect because as stated, constructors cannot be overridden in Java.
