Q1. If you are given choice to either load object eagerly or lazily , which one would you use in case of singleton pattern ?

Design

Ans. I would choose Eager as the cost for 1 additional object is too minute for any such consideration.

Eager Loading results in Faster access ( Object available at load time) at the cost of additional space.

Lazy loading results in space saving ( Object available at first use ) at the cost of access speed.
