>>>Observe that there is no way doA() can be accessed.
fyi...

Code: Select all

class TopClass
{
    public Inner inner1 = new Inner()
    {
        public Inner doA(){  
            System.out.println("doing A"); 
            return this;
        }
    }.doA();  // call doA() here

    public void doA() { inner1.doA(); }
}

class Inner
{
   int value;
}

Assuming that you are trying to show a counter example, have you even tried to compile your code?

[Harvey Manfrenjensen]

you are right, it does not compile, i took it from the explanation of question,
which show inappropriate call of a new method of anonymous class.
Here is example, that compiles.

Yes, this compiles but this is not the doA() that is given in the problem statement.

Your code does show an interesting way to invoke a method of an inner class though.
