Java Tutorial - Command Line Arguments

Command Line Arguments in Java

This is a short and simple video tutorial to illustrate how to use and process command line parameters in Java. It covers all of the basics necessary to get you started with command line parameters and using them in a practical way. In particular, I will illustrate the answers to the following five questions:

Q1- What exactly is a command line parameter (or command line argument)?

Q2- How to determine if any command line parameters were passed to the program?

Q3- If so, how many command line parameters were received by the program?

Q4- How to identify and process each individual parameter when given an arbitrary number of parameters?

Q5- This is a questions that most beginners struggle with - how to read in and process a non-string parameter, such as an integer?

As always, I hope you enjoy the video and find it useful. Please leave any questions or feedback you may have in the comments section and I will get back to you. Thank you!
