Join Peggy Fisher for an in-depth discussion in this video Getting started with parsing, part of Java Essential Training for Students.
- 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 loop through all the values in the A-R-G-S array,…
