The prefix sum in comes from the mathematics. The set of all managers is contained in the set of all employees and is therefore a subset of the set of employees. To mock a class use the keyword In the above example the class is a base class and the class is a subclass of the class. The class abstracts the basic characteristics of all employees of the company: first name, last name, salary, and date of hire. The class supplements these characteristics with the manager's bonus percentage and changes the behavior of the methods of the base class using polymorphism.
Polymorphism When considering polymorphism you need to remember that this principle is B2B Fax Lead inextricably linked to another principle of imitation which helps achieve polymorphism. Let's take the example of an abstract class followed by two concrete classes: Sports Car and Truck. Both sports cars and trucks will have common characteristics and be able to perform actions common to all cars specified in the abstract parent class but the specific implementation of these actions may differ. For example, the starting action common to all cars can be achieved by pressing a button in a sports car and by using a key in a truck. A solution with different results.
More precisely polymorphism is one of the principles which allows calling an overridden method through a parent class variable to obtain behavior corresponding to the actual derived class referenced by that variable. The code above gives an example of polymorphism. First assign the variables of the parent class to the object of the subclass. When the method is called the console will output When the same variable is further assigned to an object of the subclass and the same method is called the following will be displayed on the console Abstraction Lately abstraction has started to be singled out as a separate fourth principle.
