UML Diagrams and Class Relationships

UML (Unified Modeling Language) is used to visualize the design of a system.
Abstract classes in UML are represented as a class with italics or a special notation.
The given code describes an abstract class People, which has properties for age and name and an abstract method printInfo().

Class Hierarchy

People is the superclass from which other classes derive.
Two classes inherit from People:
- Student class has an additional property grade.
- Teacher class includes an additional property experience.

Key UML Representation

The relationship depicted is a generalization relation, illustrated as an inheritance arrow pointing from Student and Teacher to People.
Subclasses must implement the abstract method printInfo(), ensuring they provide specific information.

Importance of UML in Software Development

Facilitates communication among developers by providing a clear structure.
Captures system requirements and designs, aiding in the planning and documentation process.
