Boundary condition handling is an important aspect of Object-Oriented Analysis and Design (OOAD) that ensures a software system behaves correctly during exceptional or transitional situations. Boundary conditions refer to the states that occur at the beginning of system execution, during system shutdown, or when unexpected errors and failures arise. Proper handling of these conditions improves system reliability, maintainability, security, and user satisfaction. In object-oriented systems, classes and objects are designed not only to perform normal operations but also to manage these special situations effectively. Initialization mode refers to the activities performed when the system starts. During initialization, the software prepares itself for execution by creating objects, allocating memory, establishing database connections, loading configuration files, initializing variables, and validating required resources. In OOAD, constructors play a significant role in object initialization. They ensure that every object begins its life in a valid and consistent state. Initialization also includes verifying user credentials, checking network availability, loading external libraries, and preparing the user interface. If any required resource is unavailable, the system should notify the user and either retry the operation or terminate gracefully. Proper initialization prevents errors during later
