If A is a class..den what will A.class return??

[Aarti Gauba]

if A is a class.... what is A.class??? and if aa is an object of class A....den what will aa.class return?? A.class is returning "class A" ... but what is dis class?? is it a variable in Object class? what is the relaton between Class & Object class??

Very disturbing question...not exact but some related stuff

We have A.java as a source file having a public class "A" and "aa" as A's object. When you compile A.java, you get A.class. Every class is a subclass of Object.
----
Now if you print A.class in A.java , it comes as "class A"
If you try to get "aa.class" , its a compiler error as "aa" isnt a class!
----
We have a class java.lang.Class (extends Object).Instances of the class j.l.Class represent classes and interfaces in a running Java application.
j.l.Class objects are constructed automatically by the Java Virtual Machine as classes( like A.class) are loaded and by calls to the defineClass method in the class loader.

----
refer Class Loaders and java.lang.Class to understand more and post here if you get the exact answer.

A.class represents the java.lang.Class of Class A.

If aa is an object of A and if you want to get the Class to which aa is an object, use aa.getClass(). It returns the same java.lang.Class.

A.class and aa.getClass(), both Upon printing prints the class name in a readable manner along with the package name.


aa doesn't have an attribute called class. So aa.class won't compile.
