Method Detail |
public Object previous()
previous
in interface BidirectionalIterator
ListIterator.previous()
public int back(int n)
The effect of this call is exactly the same as that of
calling previous()
for n
times (possibly stopping
if BidirectionalIterator.hasPrevious()
becomes false).
n
- the number of elements to skip back.
