actionPerformed method problem for filechooser

[vicky ma]

Hi,
I have question on actionPerformed method.
does this method runs on thread ?

as i can see in my code i have scenario as below :
(Its abstract from my code base : )

class A {
string path;    // Set to class path
	  public void actionPerformed(ActionEvent e) 
          {  
                    // HERE I GET PATH OF SELECTED FILE USING 
		    JFileChooser chooser;
		    chooser = new JFileChooser(); 
		    path =   chooser.getSelectedFile().toString();
          }

}

class B {
        public boolean printpath()
	{
              A obj = new A();
		      System.out.println(obj.path);
	}

}

here whenever i print that path string i get null .
how to get path which is set in action method ? please provide example so that i can understand it.
Thanks

PS : Its ABSTRACT !

What is abstract?

From what code you have posted, I see two problems to start with
1) Nobody is calling actionPerformed
2) You are not showing the file chooser dialog.
