    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.

    Skills covered in this course

  • Welcome

    - It is helpful to understand how to compile and run Java programs without using an integrated development environment. For this section, we will use Brackets as our text editor to write Java code and then compile and run the programs using the executables available from the Java Development Kit, or the JDK. All Java applications are compiled to bytecode that can run on any JVM, or Java Virtual Machine, regardless of the underlying computer architecture, making it platform independent. A Java application can accept any number of arguments from the command line. This allows the user to specify configuration information when the application is launched. To write and test programs using the command prompt, it is important to locate the folder where you downloaded the Java JDK. This is required to compile and run Java programs on your machine. When you installed the JDK, along with your IDE such as NetBeans, the default directory for Windows should look similar to this, c:\Program Files\Java \jdk1.8.0 _31 We will use this information to set the path variables so we can compile and run our program from the command line. To open a command prompt, we go to the Windows icon and type CMD.
