Builder Design Pattern is a creational design pattern. It is used for creating complex objects by isolating construction process from the representation. By doing this, same construction process can create different representations. Also, implementation of construction is decoupled from the representation by using builder design pattern. So, when we have…

Java Reflection API is an advanced feature of Java used for introspecting and modifying applications from class levels during runtime.
