Getting a Component name as a string

Say I make an object, a control.

JButton Button_1 = new JButton("whatever");

now say i want to retrieve the name of the JButton, that is
"Button_1", as a string. How do i do this. I have extended buttons
with a setName()/getName() method but there must be an easier way than
wrapping every object i want to do this with. It is probably really
simple and I'm probably a total clown for not knowing, but any pointer
to where i can learn more about this would be appreciated.

Would that be a question?

If so - you might approach this by checking the methods
listed in the API JavaDocs for JButton.

What happened when you tried that?

your sarcasm is always a delight.
i dind't see anything at a brief overview of that but no doubt i was
looking in the wrong place. Also the object i am working with is not a
JButton, It's a custome made extension of FileFilter, a custom
extension of some Components, and a few homemade objects as well, so
a more global solution is necesary

You're welcome. Any time you should slouch in here
asking such apparently stupid questions.

> i dind't see anything at a brief overview

By 'brief overview', what do you mean?

Do you mean "After reading the docs on the 'get' methods
of JButton and it's superclasses.."?

Presuming you did that, then, no, that would be the right place.

>..Also the object i am working with is not a

So.. what was the point of your example that mentioned
a JButton?

>..a custom
> extension of some Components, and a few homemade objects as well,

Extending what? java.lang.HomeMadeJam ?
No? Perhaps you can fill in the details there..

>..so a more global solution is necesary

Tried the UN?

"control" is a Windows term. Please adapt common Java terminology so we
know what you want. Oh, and please don't even attempt to use HTML in
Usenet posts. Many people will ignore you already just for trying.

No, that is not the name of the button. That is the name of a variable
which can hold a reference to a JButton, any subclass of a JButton or no
reference at all (null).

You lack some basic understanding of the Java language. Consider a good
introduction textbook.

If you base your application design on naming things this way, then your
application design is seriously flawed. This smells like a severe lack
of understanding objects. An object is characterized by state, behavior
and identity. And the identity is not a name, but in the case of Java
the unique reference each object has. Variables holding identical
references are guaranteed to reference to the same object. An attempt to
establish an own identity system is at a minimum an attempt to re-invent
the wheel and a serious waste of time.

A good Java introduction textbook.
