    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.

      Peggy Fisher

      Lecturer at Penn State University

      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

    - So how did you make out with the challenge? How is your name game working? Let's take a look at my solution, and as always, remember that your solution might be very different. As you can see in the "main" method, I have the two dimensional array of names, and then I added some additional code. I wanted to allow the user to execute the program more than once, so I declared a string variable, "response", and set it equal to "y" the first time. I also declare a string variable, "name", that's gonna hold the name the user would like to search for. My "while" loop says, while "response" is equal to a "y", ask the user to enter the name to search for. Then we'll read the name in, using the "name=in.nextline", on line 32, then I call my "searchName" method, and I give it the two dimensional array called "names" as well as the name that I'm trying to search for. If the value that comes back from the method is true, I print out the message saying "The name was found"; otherwise, I print out…
