Because $item is of type java.lang.Object, $item.getClass() yields a
java.lang.Class representing the class of $item, which has a method
getName() returning a java.lang.String containing its fully qualified
class name.  Using Velocity's shortcut syntax which allows us to write
$ref.getSomething() as $ref.something, then the expression

    $item.class.name

will give you the fully-qualified class name of $item.

If, as in your example, you don't need the classname as a string, then
the expression
  
    $item.class.equals($A.class)

will tell you whether A is an instance of typeA.  Or, if typeA is a
java.lang.Class of the type that you want, it would be

    $item.class.equals(typeA)

For other possibilities, you have all the public methods of
java.lang.Class.
