Hi miria,

Ofcourse, The class with default acess is visible to all classes within the same package. so the default class can be subclassed(extend another class).

  
class Test extends Test1
{
public static void main(String[] args)
{
Test1 t1=new Test1();
t1.one();
}
}
 
class Test1 
{
public void one()
{
System.out.println("This is Test1 class");
}
}
  

Here the class Test with defaul acess extends the class Test1.
output : This is Test1 class

Is this you are expecting...?

I assume you mean a class that isn't public by saying it's default.

Yes you can subclass it. You can even put the default and its subclass in the same file if you like (remember you can have multiple classes in a file but only one top-level class can be public). At the very least the subclass must be in the same package though, because of visibility.

You can even make the subclass public if you like. It wouldn't be likely you'd ever want to do this but you could.

Unfortunately, your name "miria" does not comply to the naming policy. Your display name should consist of a real-sounding first name, space, and a second name. Not only a first name, no obviously fake nickname, no initials only for the second name.

Please read the naming policy carefully and change your display name. You can change your name by editing your profile.
