You would get a better response if you post this question in The Java Forum.
Here is a link that explains all java data types including default values: Data types

Perhaps your interviewer should have started by asking you the difference between Java[^] and JavaScript. Apart from some vaguely similar syntax, they're completely different things.

I'm trying to setup a shopping cart form function (add to cart button) which is called via a java script - I have this in a pop-up window and want to have the "add to cart" button both close the pop-up window and also load the info in the main window - anyone know what script modifications I need to have?
here is part of my current code in the pop-up window:
any help would be super!

If you are having this button in popup, then it would not be possible to get control of main windows once you close this popup right.
So my suggestion would be to have a js file common to both main window and popup.
And have a js function in it to close the child window and then trigger update on main window.
On click of add to cart button, trigger this function.
Hope this should be helpful.

Thank you for the help - if you had some code that would help me please let me know - thanks

First thing you'll need is to store the reference of the popup window.
Then you can use it to close the popup and refer to window.location object for updating the page as shown below.
var childWin = window.open(url,name,params)
function closeWindow()
{
childWin.close();
window.location.href = "<new url>";
document.getElementById("divId").innerHTML = "<updated html>";
}
If you want to just update a part of the page, then you can handle it through the DOM objects (document).

here is my complete add to cart code:
<form class="cart" action="index-shop.php" method="post"><input type="hidden" name="my-item-id" value="book 1" /><input type="hidden" name="my-item-name" value="book 1" /><input type="hidden" name="my-item-price" value="35.00" /><input type="hidden" name="my-item-url" value="http://www.amazoni.![enter image description here][1]com" />Qty: <input type="text" name="my-item-qty" value="1" size="3" /><input class="button" type="submit" name="my-add-button" value="add to cart" /></form>

I won't be able to change this code.

better if you stay on current window. Use jquery dialog for this kind of scenario.
html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery UI Dialog - Default functionality</title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">
<script>
$(function() {
$( "#cart" ).dialog();
});
</script>
</head>
<body>
<div id="cart" title="Basic dialog">
<p>Use cart item to add in cart list.</p>
</div>
</body>

Yes, this should work as well.

can i send the email by javascript on html web form.
|
|
|
|

Your javaScript would have to call a webservice because JS executes on the client machine so it cannot send email. You can use the jQuery library and call .ajax() to call your webservice to send the email.
There are only 10 types of people in the world, those who understand binary and those who don't.

I recently added tinymce to a site I'm developing, and other javscript code appears to have stopped working as a result. Is there an easy way to find conflicts that could cause problems?

I use Internet Explorer, the F12 Key.
IE11 F12 is pretty slick now, You choose the debug mode, the icon of a bug, load your page, and the cursor in the F12 box will stop on error, and give you an idea of the error. to continue, right click and choose "Run to Cursor"
Some of the messages are vague, so then you just search the message text for an answer.
For stuff I write, I run it through JavaScript Lint, to check for errors.

This is a piece of the code I'm working with and the only part giving me problems. I'm using the combo box to give me both the Line2_flag and the screencharge. Without this particular piece of code the form works fine so I know it's just this snippet. Any help is appreciated. Thanks!
<select name="inkcolors" size="1" id="inkcolors" class="FormStyle"
<option selected value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
var = Line2_flag;
var = screencharge;
if(form.inkcolors[1].selected){
Line2_flag = 1.75;
screencharge = 1;
}
if(form.inkcolors[2].selected){
Line2_flag = 2.25;
screencharge = 2;
}
if(form.inkcolors[3].selected){
Line2_flag = 2.75;
screencharge = 3;
}

You may like to explain what the problem is.

Sorry I wasn't clearer, but I did receive my answer on another site so I will post it here in case it helps.
<html>
<form>
<select name="inkcolors" size="1" id="inkcolors" class="FormStyle"
<option selected value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</form>
<script>
var Line2_flag = null;
var screencharge = null;
var field = document.forms[0].elements['inkcolors'];
var selected = field.options[field.selectedIndex].value;
if (selected === "1") {
Line2_flag = 1.75;
screencharge = 1;
} else if (selected === "1") {
Line2_flag = 2.25;
screencharge = 2;
} if (selected === "3") {
Line2_flag = 2.75;
screencharge = 3;
}
</script>
</html>

All well and good but you still did not explain what the original problem actually was.

Are you sure this is right?
You're checking for selected === "1" a second time in the else if, so the middle section will never execute.

If you're in your final year, you should have learned the difference between Java[^] and JavaScript by now. Aside from a vaguely similar syntax, there's no connection between the two.
