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.

- Welcome back. How did you make out with your challenge? I hope you were able to find the errors. I'd like to show you how I would approach this problem. As I stated earlier, the first thing is to figure out what the expected results should be. The first part of the code allows the user to enter a set of numbers and find the average. The second part says, "Okay, I'm gonna give you "the numbers, three, five, and eight, "add them together, divide them by three "and print out the average." And the last part is converting from Fahrenheit to Celsius. It's starting with a Fahrenheit value of 212. So my expected values, for the first part I'm gonna enter three numbers; 10.5, 15, and 7.5. So I expect the total to be 33 and the average to be 11. On LIne 28, it should print out the average of three plus five plus eight divided by three which should be 5.33 repeating. And finally, using the formula for Celsius equals 5/9 times Fahrenheit minus 32. I know if Fahrenheit is 212 the Celsius should…
