Scala OOP: Defining and Using Classes
In Scala, a class is a blueprint for creating objects. It encapsulates data and behavior, defined as fields and methods. Classes can have parameters, which are passed during object creation. They support inheritance, allowing the creation of subclasses that extend base classes, enhancing code reuse and organization. Understanding how to define and use classes is fundamental for object-oriented programming, facilitating the creation of robust and maintainable software systems.
The code defines a Person class with name and age parameters, and an Employee class that extends Person, adding an Id parameter. The displayInfo method is overridden in Employee to include the employee ID. Instances of both classes are created and their information is displayed.
