Answer 1

Answer:

(A) is the answer INITIALIZATION

Answer 2

Option (C) is correct.

Using the "Initialization and Constructor function" we can be used for a servlet.

About Constructor Vs Servlet :

• Although constructors are permitted in Servlet methodologies, they should initialize the Servlet using the init() method for two main reasons: first, constructors cannot be expressed on an interface for Java, and secondly, constructors cannot be defined on an interface in Java.

• In Java, interface constructors can indeed be defined. Any class that respects the Servlet interface is therefore exempt. In addition, Servlet needs the container's ServletConfig object for initialization.
