      • Peggy 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

    - I hope you didn't find this challenge too bad, but I wanted you to get used to using the Oracle documentation to find libraries and classes that may exist that may be helpful in the future. If you went out to the Oracle site, and looked at the Java API, I hope you found that the java.text library has the date formatting that we need. There's also one little secret that I didn't mention, and that's that the IDE is very helpful when it comes to missing imports. Let me show you what I mean. As you see, right now, the program does not know what DateFormat and SimpleDateFormat are. If I move my mouse over to the lightbulb with the exclamation point on it, and if I left click on that, I'll get a list of options. It says, "I can add the import for you," and you'll notice, it says, Add import for java.text. That's the library that I need, that DateFormat. I'll click on that one first. But I need both, I also need the SimpleDateFormat, so I'll go back over, and click on that one too. There…
