| | Chaps, today I was reading about exception handling and although the book explains them in sufficient details there is something that I really struggle to understand. Ok, here's the example they analyze: // Fig. 11.2: DivideByZeroWithExceptionHandling.java // Handling ArithmeticExceptions and InputMismatchExceptions. import java.util.InputMismatchException; import java.util.Scanner; public class DivideByZeroWithExceptionHandling { // … |
| | Chaps, I have a question about nesting elements. I am using bootstrap for a project I am working on, and for whoever didn't know that - I am one of those - in bootstrap buttons are `display:inline-block;` Now, I have this situation at the moment: `<p><button>My button</button> This button means … |
 | Hi, the gap is there because both the `td` and the image have a height: <td width="600" height="11" border="0" style="padding:0px;" colspan="2"> <img width="600" height="11" style="vertical-align:top;" src="xxxxx"> </td> Now, this `tr` <tr> <td width="600" height="11" border="0" style="padding:0px;" colspan="2"> <img width="600" height="11" style="vertical-align:top;" src="xxxxx"> </td> </tr> to me doesn't look like is …  |

| | Hi guys, I was wondering whether it is alwasy true that a button needs to be inside a form tag? Is that necessary all the time? > The W3C say that The FORM element acts as a container for controls so kind of yes really, but I 'd like to … |
 | I have started to use Bootstrap quite recently, personally I think it's just a waste of time, but anyway, I think the reason why it is breaking is because you are using the table inside the grid - if I understand correctly what you're saying. My suggestion is to get … |
| | Chps still having big problems uploading java files onto the forum, I keep getting the below error  |
| | To start with, I'd say that rather than relying on the width of the label to position the input, you should remove that `width:8em` and give the input a margin-left. The input is a block element so you can safely have a margin applied to it. I am using linux … |
| | Hi guys, I need to buy a new battery for my Samsung galaxy GT-I9000, because the one I currently have doesn't hold charge for that long. I wonder, do you think it is safe to get one off ebay/amazon, or is it better to get a samsung's? thanks |
| | Hi chaps, I am looking for a not too difficult exercise which involves superclasses and subclasses (the java book I am reading doesn't really have any good one).

| | Chaps I have an interesting and odd problem.

It is all nice and dandy till I placed the graph inside a hidden container, planning to add some jquery and slide the graph down … |
 | To be honest with you @yaragalla_mural I don't like the way you have positioned the elements in your code, there is no need to position elements relatively if you can achieve pretty much the same effect with padding for the sake of argument. Check this code out and adjust the …  |
| | Re: HR tag line If it helps, I try not to use hr anymore, anytime I need to achieve the same effect I will just use the css border property, it is much more reliable and works pretty much all the time in every browser. So say you have a `<div class="myDiv">...</div>` then just … |
