how to find the class of an object?

[Sean Anderson]

If I pass an object reference(JComponent) to a method I want to be able to
find out what class of omponent it is; JTextField, JComboBox etc...

Is there a way to do this? No "comparable" bull please.

Component bb = MORE_BTNPANEL_REFERENCES[mwindow].getComponent(index);

if(bb instanceof JLabel) {...}

Component bb = MORE_BTNPANEL_REFERENCES[mwindow].getComponent(index);

if(bb instanceof JLabel) {...}

and more generally,

Class bbClass = bb.getClass();

See http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Class.html

Also, How on earth *would* you do this with comparable?

How about

public static void someMethod(Object obj) {
Class theClass = obj.getClass();
String nameOfClass = theClass.getName();
}
