Calling Methods of Anonymous Inner Class in the parent class

anonymous-class, java, overloading

Solution

You cannot do this with an anonymous class; it conflicts with Java's static type system. Conceptually, the variable `fAnon` is of type `father`, which has no `.method(String)` or `.newMethod` methods.

What you want is an ordinary (named) subclass of `father`:

class fatherSubclass extends father
{ /* ... */ }

and you should declare your new variable

fatherSubclass fAnon = new fatherSubclass(d)

Problem

I got the below doubt when am surfing about Anonymous inner class Here is the Original code I downloaded and was working around it (please refer to the below code only for my questions). As per the link above they say we cannot overload & add additional methods in a Anonymous Inner class. But When I compile the below it was working fine though I was not able to call those public methods outside the Inner class. Initially I was surprised why I could not access the public methods outside the Inner class but then I realized the Object is being held by "father" class reference which does not know such function call. What changes Can I make in the below code for making calls to the overloaded method and new Method outside the Inner class? ``` class TestAnonymous { public static void main(String[] args) { final int d = 10; father f = new father(d); father fAnon = new father(d){ // override method in superclass father void method(int x){ System.out.println("Anonymous: " + x); method("Anonymous: " + x); //This Compiles and executes fine. newMethod(); //This Compiles and executes fine. } // overload method in superclass father public void method(String str) { System.out.println("Anonymous: " + str); } // adding a new method public void newMethod() { System.out.println("New method in Anonymous"); someOtherMethod(); //This Compiles and executes too. } }; //fAnon.method("New number"); // compile error //fAnon.newMethod(); // compile error - Cannot find Symbol } public static final void someOtherMethod() { System.out.println("This is in Some other Method."); } } // end of ParentClass class father { static int y; father(int x){ y = x; this.method(y); } void method(int x){ System.out.println("integer in inner class is: " +x); } } ```
