How to get String out of void method

Question

I have a problem to get String out of void method. I override method actionPerformed(), and I need to use String from this method in other methods. I get nothing in smth. Can anyone help me with this.
class
StringBuffer smth = new StringBuffer();
StringBuffer s;
      public void actionPerformed(ActionEvent event){
          String vnos;
          if(event.getSource() == btn_vnos){
               input = field.getText();
               s = new StringBuffer(input);
                smth = s;
            }             Thanks

You have needs to use a static variable or somehow pass an instance reference, through a list or array or some such thing, perhaps through the constructor. Or think up some other jazz, like adding a method "public String getMyStinkin'String" ;~)
