OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

1. Employee and ProductionWorker Classes Write an Employee class that keeps data attributes for the following pieces of information: Employee name Employee number Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: Shift number (an integer, such as 1, 2, or 3) Hourly pay rate The workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen. 2. ShiftSupervisor Class In a…

Design a class named Pet, which have the following fields: • Name - name of the pet. • Animal - type of animal that a pet is (Dog, Cat, Bird). • Age - age of the pet. The Pet class should also have the following methods: • setName • setAnimal • setAge • getName •.getAnimal .getAge a) Draw a UML diagram of the class. Be sure to include notation showing each field and method's access specification and data type. Also include notation showing any method parameters and their data types. b) Write the Java code for the Pet class. Create a main method in the same class and instantiate at least two objects of the class.
