Simple explanation of (string[ ] args) wanted

[gopostal703]

Hey guys, I have been doing java for some time now( though not for that long ) and I see that after public static void main, I always add (string[ ] args) because all books include it and everywhere I go I see it. Is it for providing an argument to the main method or what? Please explain to me in terms 14 year old would understand:). I'm learning Java because you can do so much with it and I want to take up jobs on elance and earn some money.( I just got an ipad 3 with money I earned from mturk) Thanks in advance!

Have a read of A Closer Look at the "Hello World!" Application in Oracle's Tutorial - especially the section headed "The main Method".

Have you tried writing Java code in a text file and compiling it using the command line 'javac' command then running with the 'java' command? it looks like this...

java MyJavaClass

if you have then if you do this instead

java MyJavaClass argument1 argument2 argument3

everything after your classname 'MyJavaClass' gets passed into your Java program through the 'String[] args' so that in your Java program

args[0] will be equal to 'argument1'
args[1] will be equal to 'argument2'
args[2] will be equal to 'argument3'


...does that make sense?
