    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.

    - Sometimes when writing your programs you might want to create the same method twice, but with slightly different values as arguments or maybe even a different return type. Two or more methods may have the same name as long as the list of parameters or arguments or the return type is different. When this happens it's called Overloading. You Overload the method. For example, if you want to write a method that finds the average of three numbers you might want to allow it to use three integers, but you also might want to allow it to use three doubles. The logic is the same but the type of data sent by the calling program is different. So you would create two methods with the exact same return type and the exact same name but they would each have different arguments. One would have three INTS and one would have three doubles. Again, this is called method Overloading. Now let's take a look at the example I have here. I have updated the program we worked on the last section to calculate…
