   {
    a = 10;
   }

abstract public void set();

abstract final public void get();

}

class Test extends demo
{

public void set(int a)
{
    this.a = a;
}

final public void get()
{
    System.out.println("a = " + a);
}

public static void main(String[] args)
{
    Test obj = new Test();
    obj.set(20);
    obj.get();
}
}
