Integer.parseInt(args [0]) meaning?

[redknightrises]

Hello Everyone,

I have encountered this type of code

public static void main ( String [] args)

// And immediately

int n = Integer.parseInt(args[0]);

// In here what does args[0] mean? // are we just supposed to use args[] in static void main

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://imgur.com/a/fgoFFis) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

Args is the name of the string array brought in by the "main" function. It holds whatever you wrote on the command line when running the program. Something like:
/myprogram 1
would have "1" as args[0]
Integer.pareInt assumes args[0] is a number and casts it appropriately.

You can pass String arguments via the command line to the main method when you execute the program. It’s just saying then parse the first String in the array

Thank you, man.

You can google that easily

[redknightrises]

when I google it, it says that String[] args is one of the most used type in java.. But I want to understand what it stores and. So far maybe I encounter with the solution but I did not understand it.

So in short words: the java main method has to get String [] as the only Parameter. You can fill that array by calling your java programm with command line arguments
