Non anonymous class

Question

I have a doubt in the following piece of code, Here JPanel class is getting two extra methods, how does this works and what do we call this kind of class in programming language terms. Where can i use it.
public class XYX {
// constructor goes here.....
public void displayXYZ(){
  JPanel panel = new JPanel(){
       public String getPanelID(){
            return "SOMEID";
       public void delete(){
          // do delete operation .
  // some more logic here
}TIA

Answer 1

i got it....
I have one more doubt..
Consider this example.
public class XYX {
// constructor goes here.....
public JPanel displayXYZ(){ 
JPanel panel = new JPanel(){
      public String getPanelID(){   
        return "SOMEID";
      public void repaint(){ 
        // repaint in my way operation . 
   // some more logic here
return panel;
}I have overwritten repaint() method of JPanel now if i issue a repaint() method it should repaint in the new way. IS that right.
The second doubt is, I create this panel and i am returning it in this method is that possible to do that, will i still have a reference to this new JPanel, what are the effects of doing so.
How to use reflection to access anonymous classes.
TIA
