    Basic method of passing command line argument in java is as follow

    java <program name> a1 a2 a3 .....

    Now for declaration of command line argument we use this statement ,which is must for every java program

    public static void main(String args[])

    array can be declared as shown below

    int a[]=new int[6];

    Now since command line argument are in string form you can convert it into integer form by using this

    int n=Integer.parseInt(args[0]);

    For rest ,i hope you can use your programming skills. 😀
