Class extends JComponent how to use custom methods?

Question

I have a class Block which extends JPanel
code is hereprivate class Block extends JLabel{
          boolean top;
          Block(int a,Color c){
               setSize(40 + a*10,20);
               setBorder(BorderFactory.createMatteBorder(40+a*10,0,0,0,c));
          void setTop(boolean b){
               this.top = b;
          boolean getTop(){
               return top;
     }I need to use getTop() method of certain block in class implementing MouseMotionListener
I used getComponent() method like this
e.getComponent().getTop()but it didn't work and gave
HanoiTowers.java:59: cannot find symbol
symbol : method getTop()
location: class java.awt.Component
if(e.getComponent().getTop()){}
error
Is there some other way to do this?

Is there some other way to do this?You could cast I suppose:
          Component c = e.getComponent();
          if (c instanceof Block)
            System.out.println(((Block)c).getTop());
          }
