Is there an alternative to operator instanceof to be more dynamic

Question

Is there a way to check whether an object is an instance of a class when the name of this class is not known at compile time. For example :
Let's assume I have 3 classes TestBean1, TestBean2, TestBean3
which extends the super class TestBean.
The objective of the TestBean super class constructor is to check whether a user is granted (according to a profile) to execute a particular TestBeanX (X= 1, 2 or 3) class.
The obvious advantage iwould be to avoid the same code to be repeated in each subclass.
The source code below works fine. However everytime a new class inherites from the super class,
TestBean has to be updated to include a specific class code checking.
Is there any way to make this more dynamic ?
To be more concrete, instead of the instructions :
res = "?????";
if (res.equals("TestBean1") && this instanceof TestBean1) .....
I'd rather like to have something like :
if (this instanceof res ) .....
which of course and unfortunately does not work. Is there an alternative to this kind of code ?
Thanks a lot.

import java.io.*;
import java.util.StringTokenizer;
class TestBean
public TestBean(String userid)
     // String ACL = getProfile(userid); // return a list of authorized Beans
     String ACL = "TestBean1 TestBean3" ; // just for testing purpose      
     StringTokenizer st = new StringTokenizer(ACL);
     String res=null, msg=null;
     while (st.hasMoreTokens())
     res = st.nextToken();
     if (res.equals("TestBean1") && this instanceof TestBean1) { msg=res; break;}
     if (res.equals("TestBean2") && this instanceof TestBean2) { msg=res; break;}
     if (res.equals("TestBean3") && this instanceof TestBean3) { msg=res; break;}
     if (msg == null)
System.out.println(userid + " is not granted to run this bean");
     else
     System.out.println(userid + " is auhtorized to run the bean " + msg) ;
class TestBean1 extends TestBean
public TestBean1()
{   super("Gerard");
System.exit(0);
public static void main(String[] args) {new TestBean1();}      
class TestBean2 extends TestBean
public TestBean2()
{   super("Gerard");
System.exit(0);
public static void main(String[] args) {new TestBean2(); }      
class TestBean3 extends TestBean
public TestBean3()
{   super("Gerard");
System.exit(0);
public static void main(String[] args) {new TestBean3();}

Thanks Ken however by investigating more, I have found a good way by using getClass().getName().
I modified my code as follows and it works fine now. thanks again:
Gerard
import java.io.*;
import java.util.StringTokenizer;
class TestBean
public TestBean(String userid)
String myclass = this.getClass().getName() ; // get class name
     String ACL = "TestBean1 TestBean3" // list of authorized Beans
     StringTokenizer st = new StringTokenizer(ACL);
     boolean ok = false;
     while (st.hasMoreTokens())
     if (st.nextToken().equals(myclass)) {ok = true; break;}
     if (ok)
     System.out.println(userid + " is auhtorized to run the bean " + myclass) ;
     else
System.out.println(userid + " is not granted to run this bean");
}
