    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.

    - In our demo program we did not pass any arguments to the main method. There are times when the user needs to enter command line arguments when invoking the application. Let's create a new program to take in a message and then echo back each string on a seperate line. In the text editor brackets, we will create a new program and call it DemoWithArguments.java and save it to our My Java folder on the C drive. I want to go ahead and save this program as DemoWithArguments.java I'm gonna navigate to My Java folder and I'm gonna click Save. We'll start by declaring the class, public class DemoWithArguments. Don't forget, this name has to be the exact same name as the file name. Okay, inside the class I'll add my main method, public static void main. And in the parentheses for the main I'll have the argument, an array of strings, and usually we give it the name A-R-G-S to represent arguments. The code for my main method is gonna be fairly simple. I'm going to use an advanced for loop to…
