The above code does not display anything
<% String [] favFood = {"Ice cream", "Chocolate", "pizza"}; %>
Food: ${favFood["0"]}

But if I make the following changes it works fine

<% String [] favFood = {"Ice cream", "Chocolate", "pizza"};
request.setAttribute("favFood", favFood);
Food: ${favFood["0"]}

Why do I have to set the array as an attribute? Why can't I access it on the same page without setting it an an attribute.

The EL needs to find the variable(and its value) in some namespace. The namespace it looks at are page, request, session, and application. Declaring a scripting variable does not add the variable to any namespace. Hence you have to use setAttribute.
Don't get me started about those stupid light bulbs.
