How can I get this resolved? This is a code, and every time I try to run it this error shows up "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0 at IntOps.main(IntOps.java:5)"

public class IntOps {

        public static void main(String[] args) {
            int a = Integer.parseInt(args[0]);
            int b = Integer.parseInt(args[1]);
            int sum  = a + b;
            int prod = a * b;
            int quot = a / b;
            int rem  = a % b;

            System.out.println(a + " + " + b + " = " + sum);
            System.out.println(a + " * " + b + " = " + prod);
            System.out.println(a + " / " + b + " = " + quot);
            System.out.println(a + " % " + b + " = " + rem);
            System.out.println(a + " = " + quot + " * " + b + " + " + rem);
        }
}

Please, help me to understand why it is not working. Thanks.

    You're running the program without any args, and so it makes sense that the exception should be thrown. Make sure that when you run the program, you pass in command-line arguments. Eclipse has ways to do this in the Run menu as per one of the duplicates used to close this question. – Hovercraft Full Of Eels Feb 13 '23 at 20:10

    Follow those linked questions to understand the important step you're missing before accessing members of an array (the `args[0]`). – Rogue Feb 13 '23 at 20:14
  • Thank you guys, I'm just noob at this. – David Ladino Feb 13 '23 at 20:33
  • I understand, we all were newbies at one time or another, but in the future, best to first search on the error message before asking. A Google search such as [site:stackoverflow.com java ArrayIndexOutOfBoundsException: Index 0](https://www.google.com/search?q=site%3Astackoverflow.com+java+ArrayIndexOutOfBoundsException%3A+Index+0) (please click on this link to see what it brings up and how it works) can at least give you some ideas from similar questions, and help you make a more specific and less of a duplicate question. – Hovercraft Full Of Eels Feb 13 '23 at 21:31
