Hi,
There still is "for(int i = /*1*/; i<arr.length;i++)".
Hope it helps

Hi,
Looks to me like when you copy the args array to the arr array you are
fine, but when you go to print the values you are starting at 1 and
you should start at 0.
Thank you.

Hi,
Even when i start with i= 0, i still dont get the exact number of
names entered on the command line..
here is my code:
public class BuiltInClass {
public static void main(String[] args) {
if(args.length!=5){
System.out.println("please, names must be 5 on command
line!!");
System.exit(0);
}
String []arr = new String[7];
for(int i = 0; i<args.length;i++)
arr[i] = args[i];
for(int i = 1; i<arr.length;i++)
System.out.println(arr[i]+ " ");
generateNewName(arr);
here is what i get at my output...
run:
george
Hney
Rroy
Ayilla
null
null
e
n
r
Exception in thread "main" java.lang.NullPointerException
y
at BuiltInClass.generateNewName(BuiltInClass.java:43)
