Doubt in EL

[Shruthi Sam]

In HFSJ, page no: 398

Given Servlet Code:

 
String num="2";
request.setAttribute("num", num);
Integer i = new Integer(3);
request.setAttribute("integer", i);
java.util.ArrayList list = new java.util.ArrayList();
list.add("true");
list.add("false");
list.add("2");
list.add("10");
request.setAttribute("list", list);

The question is: The following will print what?

   ${list[0] || list["1"] and true }

The answer given is "true". Can anybody please clarify this?

What i thought was...

list[0] - true
list[1] - false

it will be ${true || false and true}

${true || false}

==> false


Please clarify.

[Vijitha Kumara]

${true || false}
==> false

Is that how "||" (logical OR) operator works?
