] | You can use jQuery to select all even or odd nodes, and then apply a css class to them.
<http://api.jquery.com/nth-child-selector/>
```
$('#parentDiv:nth-child(even)').addClass('evenDivs');
$('#parentDiv:nth-child(odd)').addClass('oddDivs');
``` | CSS has no way of selecting based on a class name that changes like that.
There are various [nth-selectors proposed for CSS 3](http://www.w3.org/TR/css3-selectors/#nth-child-pseudo), but browser support is currently weak. |
2,362,577 | Lets say i have 50 element grid. If its wide list it is easy for readers if i color odd and even div differently.
Now lets say i want to do this and color code every 5th div. Is there a way to choose which css to apply based on a number? like instead of
```
<div class="odd">blah</div>
<div class="even">blah</div>

] | Yes, with [nth-child](http://css-tricks.com/how-nth-child-works/). Note that nth-child doesn't work in IE, but it is a valid jQuery selector, so you can either use this with modern browsers and pure CSS, or with all browsers and a bit of presentational JavaScript. | Assuming you can actually use numbers as css classnames, the css could look like
```
div.1, div.3, div.5, div.7
{
// Odd Style here
}
div.2, div.4, div.6, div.8
{
// Even Style here
}
```
Not that pretty, but flexible enough to do what you ask. |

] | Neither. You don't need either of these. `Collections.enumeration()` takes a `Collection` argument, and `Set` is a `Collection`, and `Map.keySet()` returns a `Set`.
You just need:
```
return Collections.enumeration(map.keySet());
``` | The use of these obsolete -though not deprecated- classes is often a business decision. There's not much you can do about it, except, if possible, use a different API.
I wouldn't use `Vector`. If you don't need the synchronisation in your own code, use the Collections Framework. If you do need the synchronisation, use... |

otherwise use Vector . |
