Examples of java.util.ListIterator.previous()

java.util.ListIterator.previous()
Returns the previous element in the list. This method may be called repeatedly to iterate through the list backwards, or intermixed with calls to next to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.) @return the previous element in the list. @exception NoSuchElementException if the iteration has no previouselement.

                int newLength = newEntry.getKanaLength();
                ListIterator iterator = list.listIterator();
                while (iterator.hasNext()) {
                    Entry entry = (Entry)iterator.next();
                    if (newLength >= entry.getKanaLength()) {
                        iterator.previous();
                        break;
                    }
                }
                iterator.add(newEntry);
