Briefly answer the following: Consider the Ben Ten character and his transformation into different Aliens, briefly discuss which OOP pillar may implement over this character. Inheritance is used for code reusability, discuss what makes difference between the “has a” relationship and “is a” relationship. List with the real-life examples. Java does not support multiple inheritance using classes due to diamond problem. Briefly explain diamond problem with code example. Differentiate among the static, final, and finally keyword. As C++ uses destructor to release space of unused object, discuss how java reclaims space from unused objects. How would you throw custom exception? How would you re-throw exception? Discuss with code example Differentiate between checked and unchecked exception. Briefly explain with real life scenario.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
