Question

public class TestSample {
    public static void main(String[] args) {
        System.out.print(\"Hi, \");
        System.out.print(args[0]);
        System.out.prin         


        

Answer 1

1. The error is because no arguments were added when the program started.
2. Since the signature of the called main method (by JVM) is public static void main(String[] args) and not public static void main(int[] args) if you want ints, you'll need to parse them from the arguments.
