    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

    - Okay, now that we've reviewed the concept of command level programming, let's dive in and get started with compiling and running our first program from the command prompt window. We'll start by creating a folder on our C drive to store our Java programs for this activity. Something to remember about the command prompt is that you can get a complete list of command level options anytime by typing in the keyword help. In order to create a new folder, I can use the command md. Before I do that, I'm gonna type in cls. This is a handy command to clear the screen. Okay, let's make a new directory. md myJava This is where I'll store the programs for this activity. Now that I created the folder, I need to change the directory to go into that folder. cd myJava Awesome. Now, let's write our first Java program in a text editor. I've already downloaded the Brackets application, which is a free text editor that you can download from the Brackets site. But you can use whatever editor that you're…
