instanceof

[amrit singh]

what this mean
"you cannot use a java.lang.Class object reference
or a String representing the name of the class as right operand
of instanceof operator"

[Bob Moranski]

you can not say if(String instanceof String)

[Sivaram Ghorakavi]

instanceof operator should only be used against the Reference of Object. If you really want to find what class time it try using isInstance(Object obj) method from class Class.

I guess what it really says is that you cannot do something as follows:
<pre>
String s = new String("some string");
Class clazz = s.getClass();
if (s instanceof clazz) {} // incorrect!
if (s instanceof "String.class") {} //incorrect!
</pre>
