It seems I should mark my post. hehe
A simple example is that if you inherit form one class,
there is one method protected, and you override it with frienly,
you will get compile error.
Try this.
class A
{
protected int i;
A(int i)
{
this.i=i;
}
}
class B
{
public static void main(String[] args)
{
A a=new A(3);
System.out.println(a.i);
}
}
