Java : Accepting command line arguments for array of objects

I have an array like of objects in my main

Number[] NumberArray;

The class Item has this definition:

public class Number {
    int a1;
    int a2;
}

I need to accept input from command line like say 1 2 3 4 5 6, such that

Number[1].a1 = 2

and 

Number[1].a2 = 3

and 

Number[4].a1 = 5

and

Number[4].a2 = 6.

How do I do this?

Please help.

In your main method:

public static void main(String[] args)

args is an array of command line parameters. To convert a String to an int, use Integer.valueOf().

For example, to get the integer value of the first commandline argument do the following:

Integer.parseInt(args[0]);

Note that this will crash if there are no arguments.
