USE JAVA

Develop the classes for the following requirements:

1. A class named Employee (general, for college)

2. A class named Instructor (more specific, for college)

3. A class named Staff (more specific, for college, HR officer, Marking staff)

Tasks:

1. Figure out the relationships among the classes;

2. Determine the abstract class, and the child classes;

3. For the abstract class, determine at least one abstract method;

4. Each class should at least two data members and one extra method;

5. Full implementation of all constructors, getters/setters and toString, and other methods;

6. Test your Java code and take screen shots

What are the Symbolic interaction Abstract of Blumer and Goffman?

Create an abstract class Employee. Your Employee class should include the following attributes:

First name (string)

Last name (string)

Employee id (string)

Employee home street address (string)

Employee home city (string)

Employee home state (string)

Write a constructor to initialize the above Employee attributes. Create an abstract method called earnings. Create another class HourlyEmployee that inherits from the abstract Employee class. HourEmployee must use the inherited parent class variables and add in attributes HourlyRate and HoursWorked. Your HourEmployee class should contain a constructor that calls the constructor from the Employee class to initialize the common instance variables but also initializes the HourlyRate and HoursWorked. Implement the Employee abstract earnings method in HourlyEmployee to calculate the earnings for a week. Note that earnings is hourly rate * hours worked.

Create a test class that prompts the user for the information for two hourly employees, creates the 2 two hourly employees objects, calls the earnings method then displays the attributes and earnings for each of the two hourly.

This chapter discusses the different types of research design and you have read about them as well. For this entry, conduct a PubMed search and find two abstracts of studies both using a cross sectional design. The abstracts may be on any topic you chose-and they do not all have to be on the same topic. In your post, include each abstract and write about the distinguishing factors of the design used, and comment on whether or not you feel there was any other way this study could have been designed. In addition comment on next steps for the topic given the findings.
