abstract class constructor

[Harshana Dias]

Hey,

Though we cant create a instance of a abstract class (call the constructor) but if we call the constructor of that abstract class via the sub class dont we instantiate the abstract class which is not possible?

eg:

abstract class Product {
int x;
public Product( int x ) {
this.x = x;
}
}

class Test extends Product {
public Test() {
super(2);
}
}


Thank You.

I would not put it that way. I would say "invoke new" instead. Calling a constructor doesn't instanciate anything. Invoking "new" does.

if we call the constructor of that abstract class via the sub class dont we instantiate the abstract class which is not possible?

No, you instanciate a concrete implementation of Product.
