I've been going over this for a while. It worked once with 4 entries. Then
it stopped working but I did not make any changes that I was aware of. The
initial test for arguments works. if it is not 3 - 6 pairs entered it will
exit and complain.
For some reason if you enter 3 - 6 pairs it runs successfully but never
outputs the end result. I put code in the loop to see if it would output
that and it does not seem to be getting that far either.
Nothing highlights in red in netbeans so there must be some logic error that
I don't understand.

public class CommandLineArguments {
public static void main(String[] args) {
// Check if a command line argument exists
if((args.length <6)||(args.length>12))
System.out.println("Please enter 3 to 6 name age pairs.");
System.exit(0);
//create variables
int agetotal = 0;
int ageaverage = 0;
int entries = args.length / 2;
//loop it to add them up
for(int i = 0; i<args.length; i++){
i++; //increment again to get the odd array numbers
agetotal = Integer.parseInt(args[i]) + agetotal;
System.out.println("current age total is: " + agetotal);
}
//divide to get the average and display it
ageaverage = agetotal/entries;
System.out.println("The average age is " + ageaverage);
}
}
