A) Making class as AbstractB) Having a Private constructorC) Making the class sealedD) Both A & B

Naveen Kumar Shivanadri

• Sep 8th, 2016

Answer is A is always correct and B is also correct only the situation when the class does not have the static methods on it (in the question, there is no mentioned that there is no static method in it)
So, only A is correct answer.
