Infinite for loop

I have the following for loop:

for (TreeMap <String, Integer> i = result; i.size()!=0; i.headMap (i.lastKey()))

{out.println("keyword = " + i.lastKey() + " ; page no. = " + i.get(i.lastKey()));

result is a tree map that contains several strings (the keys) and integers (values).

I need to note that in the process of creating result some values (i.e. strings) were repeated and therefore their values were replaced (run over).

When I run the program it just perform the loop again and again without getting rid of the last value / key pair in i in every iteration.

Can anyone explain why this is?

thanks in advance.

At first glance it looks like a problem with your ending condition. What prints out?

elimination is the last key and its value is 267.it prints out "keyword = elimination ; page number = 267" over and over (until i terminate it)Message was edited by: razlev

How does the size get reduced to zero? I see nothing that reduces it!P.S. I hate your code layout.

a. sorry about the layout. I am kind of new to this. b. shouldn't: i.headMap (i.lastKey())"throw away" the last key / value pair every time?

I think your third statement in the "for" should be:i = i.headMap(i.lastKey());That is:for (TreeMap <String, Integer> i = result;i.size()!=0;i = i.headMap (i.lastKey())) // Change

Thanks a lot, I've been agonizing about this for a good few hours!
