break out of a for loop

Hi,

I'm having a problem with a "No Such Element" exception.

I'm itterating a list with a while loop, and within that there's a for loop.

Program enters the while loop at line 2, most of the time the for loop works fine.
but at the end of the list the for loop can not go 15 times when the list has ended and throws the exception.

I thought that as it comes inside a while (i.hasNext()) that it would be ok, but its not.

Can anyone tell me how to load as many characters as are available at the end of the file (when its less that 15) and break out of the for loop and continue without throuwing the exception?

Cheers,

Phil.
Iterator i = result1.iterator();
       while (i.hasNext()){
	for (int x=15; x>0 ; x--){
	c = (char)i.next().hashCode();
	searchword = searchword + c;
	}
			
String temp = searchword;
etc.

while (i.hasNext()){          // checks for at least one more item

for (int x=15; x>0 ; x--){  // blindly takes 15 items, without executing the while.

for (int x=15; x>0 &&  i.hasNext(); x--){  // does it better, and now you can drop the while.

Please add code to handle a set of < 15 items.

;JOOP!
