skip
public int skip(int n)
Description copied from interface:IntBidirectionalIterator
Skips the given number of elements.The effect of this call is exactly the same as that of calling

back
public int back(int n)
Description copied from interface:IntBidirectionalIterator
Moves back for the given number of elements.The effect of this call is exactly the same as that of calling

forn
times (possibly stopping ifBidirectionalIterator.hasPrevious()
becomes false).- Specified by:
back
in interfaceIntBidirectionalIterator
- Specified by:
back
in interfaceObjectBidirectionalIterator<Integer>
