        Peggy's main focus is application programming in Java, Arduino, and C++. She has also worked on courses in COBOL and discrete ,athematics. Previously she was a faculty member at Penn State University's College of Information Sciences and Technology. She started out as a programmer working for a large insurance company, but after 18 years she left her job as a director of information technology to pursue her true passion teaching. She earned a master's degree in math education, and went on to teach high school math and computer science in Pennsylvania. In 2012, Peggy accepted a position as an instructional designer at Penn State, and shortly thereafter began teaching Intro to Application Programming with Java. She is a strong supporter of women in STEM. As one of the few female programming teachers, she serves as a mentor to incoming female freshmen who are considering a career in programming. She was also the K–12 outreach coordinator for the college, where she scheduled, ran, and taught summer camps for middle school and high school students. In a PBS NewsHour interview, she expressed that all students should take at least one programming class either in high school or college. Peggy enjoys constantly learning and finding new and exciting ways to bring technology to life in and outside of the classroom, such as using Arduino microcontrollers or Lego Mindstorms, to help make learning hands-on and fun.

    - To determine the required information for the employee class, you need to conduct interviews and have discussions with the end user. For our example, we want to create an employee class for a payroll program. Therefore, we've already determined that we will need the following pieces of data. The employee first name, last name, phone number, address, employee ID, department, and title. Based on the information, here is the start of our UML diagram to model our employee class. As you can see, the top rectangle contains the name of the class, Employee. The next rectangle contains the instance data about the employee. These values refer to the state of the employee. The last rectangle is the behaviors, or the methods that we'll need to be able to access employee information. We have a constructor, Employee, which is used to instantiate our employees. As well as some get methods. As you can see, this model is not complete since we still need to add set methods for each piece of data to…
