Thread: Interactions problem with compiled program

This is my program in order to find two integers that are divisible either by 7 or 11.


public class Assignment1 {

public static void main(String[] args) {

int a = Integer.parseInt(args[0]);
int b = Integer.parseInt(args[1]);

boolean divisible = ( a % 7 == 0) || (a % 11 == 0);
System.out.println(divisible);

boolean divisible2 = (b % 7 == 0) || (b % 11 == 0);
System.out.println(divisible2);
}

}


The program is compiled with no errors. However, this shows up in Interactions when I try to Run the program:

run Assignment1
java.lang.ArrayIndexOutOfBoundsException: 0

I am a beginner, so please add as much detail into the explanations as possible.
