# Top Java SequenceIterator Methods

> The top Java SequenceIterator methods take an integer argument `n` and produce result sequences of the top `n` maximum or minimum elements or their positions:

> SequenceIterator topMax(int top) | Return the top `n` maximum values in the object's sequence
> SequenceIterator topMin(int top) | Return the top `n` minimum values in the object's sequence
> SequenceIterator topPosMax(int top) | Return the positions of the top `n` maximum values in the object's sequence
> SequenceIterator topPosMin(int top) | Return the positions of the top `n` minimum values in the object's sequence

> ## Example

> Following is an example code snippet demonstrating one of these functions:

>             SequenceIterator close = quote.close.iterator();
>             SequenceIterator top10 = close.topMax(10);
>             ...
