I am trying to write a program in javascript in which there is a list of products in an array, and they are sorted in alphabetical order. However, when I enter the code into notepad, and load it up in the website format, it just displays the code I have entered, with no formatting
var products = ["Printer","Tablet","Router","Speakers","Mouse"];
Arrays.sort(products);
System.out.println(Arrays.toString(products));
This is the code exactly as it is in notepad, and in the website bit, it is displayed as one long line of all the programming

You have to surround your code with a script tag:
<script type="text/javascript">Your_code_here</script>
Furthermore System.out.println and Arrays.toString are Java functions. It seems like you have Java confused with JavaScript. I think what you are trying to do is:
<!DOCTYPE html>
<html>
<body>
<script>
var products = ["Printer", "Tablet", "Router", "Speakers", "Mouse"];
products.sort();
var productsString = products.join(" ");
document.write(productsString);
</script>
</body>
</html>Comments
If you point a browser at a URL which returns JavaScript source code, then it will display the JavaScript source code (generally not as a single line those, that suggests a further error in which you are serving it to the browser with a Content-Type: text/html header instead of Content-Type: application/javascript).
If you want to execute client side JavaScript then you need to write an HTML document and import the JavaScript using a <script> element.
Your code will then fail because Arrays and System will be undefined.

Javascript not like java ..to use helper functions in javascript as ..sort,filter,reserve....you can use underscore.js library
