Why `java.lang.ArrayIndexOutOfBoundsException: 0` with `main` method arguments [closed]

Answer 1

You need to pass arguments from the command line.Refer the official docs.

Code:

package My;

import java.text.SimpleDateFormat;
import java.util.Date;
public class Hello {
    public static void main(String[] args) {
        Date now = new Date();
        SimpleDateFormat formatter =
        new SimpleDateFormat("MMM/dd/yyyy HH:mm:ss");
        String formattedDate = formatter.format(now);
        System.out.println(formattedDate + "> Hello, " + args[0] + "!");
    }
}
