Taking a college-level programming course? Maximize your learning with these Java tutorials. Peggy Fisher explores command-level programming, basic techniques such as managing loops and creating methods, debugging Java code, working with classes and objects, and storing and sorting arrays. Along the way, she investigates the Java API and Java's capabilities for running simulations and algorithm analysis, and issues challenges to write programs that utilize all of these Java features.
Lecturer at Penn State UniversityPeggy Fisher is a programmer and content manager at LinkedIn Learning.
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.

- Are you ready for the next challenge? In this challenge, I've tried to include several of the concepts we reviewed in this section. We've been contacted by a friend who owns a pizza shop. She wants an application that supports online ordering. After talking to the owner, we decide to create the following. A pizza class that implements the comparable interface. Again, this is for a pizza shop, and this particular pizza shop offers two types of pizza Regular and Sicilian. The Regular is circular, but the Sicilian is formed in the shape of a rectangle. We will have a super class for pizza with two sub-classes, Regular and Sicilian. The comparison will be used to sort the pizzas based on size, small, medium, large, and extra large. The pizza class needs to include the size of the pizza, the type of pizza, toppings, we'll include an ArrayList of strings to allow for multiple toppings, and the cost of the pizza. The main program will ask the user for the customer name, the type and size…
