abstract class

Hello sir,
I have problem with seeing entity class within abstract class. this is the entity class that i want to get:

public class Product extends AbsEntity implements Serializable {

public class Product (){
}
@Override
Public Integer getId(){----
.
.
.
}

The class AbsEntity is abstract class and this is its code:

public abstract class AbsEntity {

public abstract Integer getId();
.
.
.
}

to run the application this is the first class to be called

public class ProductJpaController extends AbsController<Product> {
public ProductJpaController()
{

}
.
.
.
}


And this is the class where i want to see the Product class within it,Where i can't make new Object from class T
which it might be the Product class or Any other class that extends the AbsEntity class


public abstract class AbsController< T extends AbsEntity> {

T entity = new T(); //it isn't working
.
.
.
}

So, could you please help to know if I can make the Product class visible inside AbsController class

Thank you so much, Best regards...
