      • 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

    - [Peggy] Welcome! My name is Peggy Fisher and I'm going to be your instructor for this course. I'm thrilled that you decided to learn more about using generics in Java. In this course, I will provide a definition of generics in Java, then discuss the syntax associated with using this approach. Next, we will review generics as it pertains to classes, interfaces, methods, and even talk about bounded types. Generics were added to the Java programming language with Java version 5.0. According to the Java website, for enhancements included in JDK 5.0, it says, "This long awaited enhancement to the type system "allows a type or method to operate on objects "of various types while providing compile time type safety. "It adds compile time type safety "to the collections framework and eliminates "the drudgery of casting." In a nutshell, that's what generics do for us. At the end of the course, you should be able to describe generics in Java, identify existing types of generic classes…
