What does 'name' attribute signify in any java.awt component?

With the below program, am trying to find the names assigned to all the components part of the GUI.

public class AWTCounter extends Frame implements ActionListener{
    private Label lblCount;     //Declare component Label
    private TextField tfCount;  //Declare component TextField
    private Button btnCount;    //Declare component Button



    public AWTCounter(){
        this.setLayout(new FlowLayout());

        lblCount = new Label("Counter");    // construct Label
        this.add(lblCount);                 // "super" Frame adds label

        tfCount = new TextField("0", 10);   // construct TextField
        tfCount.setEditable(false);         // set to read-only
        this.add(tfCount);                  // 'super" Frame adds tfCount

        btnCount = new Button("Count");     // construct button
        this.add(btnCount);                 // "super" Frame adds button


        btnCount.addActionListener(this);
        // Clicking Button source fires ActionEvent
        // btnCount registers this instance as ActionEvent listener

        setTitle("AWT Counter");             // "super" Frame sets title
        setSize(250, 100);                   // "super" Frame sets initial window size

        System.out.println(this);
        System.out.println(lblCount);
        System.out.println(tfCount);
        System.out.println(btnCount);

        this.setVisible(true);                   // "super" Frame shows 

        System.out.println(this);
        System.out.println(lblCount);
        System.out.println(tfCount);
        System.out.println(btnCount);

    }
  . . . . . . 
}

here is the output on console:

AWTCounter[frame0,0,0,250x100,invalid,hidden,layout=java.awt.FlowLayout,title=AWT Counter,resizable,normal]
java.awt.Label[label0,0,0,0x0,invalid,align=left,text=Counter]
java.awt.TextField[textfield0,0,0,0x0,invalid,text=0,selection=0-0]
java.awt.Button[button0,0,0,0x0,invalid,label=Count]
AWTCounter[frame0,0,0,250x100,layout=java.awt.FlowLayout,title=AWT Counter,resizable,normal]
java.awt.Label[label0,20,35,58x23,align=left,text=Counter]
java.awt.TextField[textfield0,83,35,94x23,text=0,selection=0-0]
java.awt.Button[button0,182,35,47x23,label=Count]

Based on the above output, I see some dynamic names like button0/label0/frame0/...

My question:

Is label0, attribute member value of class Label? If yes, what is the attribute member name of class Label?
