abstract class Graphics

Posted by kaushik saha on January 04, 2001 at 11:53 PM

if that is the case, our own programme should work properly.But the programme written below is giving an error "a may not have been initialised".Please help in this regard.

abstract class one{
abstract void show();
void show1(){
System.out.println("This is from show1");
}
abstract void show2();
}
class two extends one{
void show(){
System.out.println("This is from show defined in class two");
}
void show2(){
System.out.println("This is from show2 defined in two");

}
}
class three extends two{
void display(one ob){
ob.show();
ob.show1();
ob.show2();
}

static void main(String args[]){
three th= new three();
one a;
th.display(a);
}
}
