Returns a list iterator over the elements in this list (in proper sequence), starting at the specified position in the list.

Usage

From source file:Main.java

/**
 *  Resizes the passed list to N entries. Will add the specified object if
 *  the list is smaller than the desired size, discard trailing entries if
 *  larger. This is primarily used to presize a list that will be accessed
 *  by index, but it may also be used to truncate a list for display.
 *
 *  @return The list, as a convenience for callers
 *
 *  @throws UnsupportedOperationException if the list does not implement
 *          <code>RandomAccess</code> and its list iterator does not
 *          support the <code>remove()</code> operation
 *//*  w  w w.j  a  v a2 s. co  m*/
