Need Java Help Java, Arraylist and removal

Every time I try to call ArrayList.remove() on an element while in a for each loop, Java throws a ConcurrentModificationException.  I need to remove an element in a for loop because in there is where I look through the objects to find objects which meet the criteria for removal.

An array and an ArrayList are two different things in Java. Also, an array in C *cannot* be expanded using realloc(). Holy cripes, please shut up and read a book.
