] | Instead of doing for(Element element:tableRows), Elements has a size method.
So, you should be able to just do some validation with the size, and then simply
```
for(int i = 0; i < 10; i++){
tableRows.get(i);
}
```
to get 10 of them.
As for the spaces, before you store them in your arraylist just use regular ex... | Try this
```
doc.select("table.dynlist tr:lt(10)");

12,420,274 | To change all TitledBorder fonts, I am using UIManager:
```
UIManager.put("TitledBorder.font", new Font("Tahoma", Font.BOLD, 11));
```
But what to put to `TitledBorder.border` property to change only the color of the border (or maybe even it's width)?

] | Just as using `UIManager` to change all `TitledBorder` font at once, to change `TitledBorder` borders use this function:
```
UIManager.put("TitledBorder.border", new LineBorder(new Color(200,200,200), 1));
```
It will change (set) the border property to the border object passed in a second parameter.
All border type... | Well, you can always specify any property in TitledBorder itself.
Here is a fully customized example of Swing TitledBorder:

Now I need a query to return `name` as `student name` and `teacher_id` as `teacher name` by referring to the same table like below:

```
select t1.name as student_name

from table_name t1
join table_name t2
on t1.teacher_id = t2.id;

] | There's no built-in function for getting the outerHTML, but you can use this:
```
jQuery.fn.outerHTML = function(s) {
return (s)
? this.before(s).remove()
: jQuery("<p>").append(this.eq(0).clone()).html();
}
```
Then in your selector:
`$('.class1').outerHTML()` will give you what you are looking for.
