Hi Mary, In line 6 the inner class B and it's enclosing class A are instantiated and m1() is invoked immediately. In line 2 this refers to the instance of the inner class; in line 3 super refers to the superclass (SuperB) of the inner class and in particular to the value of s1; in line 4 A.this.s1 refers to the instance of the enclosing class A and in particular the value of s1. And coming back to your question line 5 refers to the superclass of the enclosing class A (SuperA) and in particular to the value of s1. Instances of class A are always instances of (instanceof) class A or SuperA. class B has no other relationship with A than being it inner class. With this I mean that it doesn't extend in any way class A. And can't be an instanceof A.
Was I clear? Best Regards,
