    }
    public void setName(String name) {
        this.name = name ;
    }
    
}


class FinalTestExtend extends FinalTest {
    public void print() {
        System.out.println("FinalTestExtend class") ;
    }
}




public class FinalDemo1 {
    public static void main(String[] args) {
        AA aa = new AA() ;
        FinalTestExtend fte = new FinalTestExtend() ;
        fte.print();
