Question

Is it any possible way to access the anonySubClassMethod method?
If no why Java compiler allowing to create this method?

abstract interface AnonyIfc {
   public abstract void methodIfc ();
}

public class AnonyImplementation {
   public static void main (String... a) {
      AnonyIfc obj = new AnonyIfc(){
         public void methodIfc() {
            System.out.println("methodIfc");
         }
         public void anonySubClassMethod() {
            System.out.println("anonySubClassMethod");
         }
      };
      //obj.anonySubClassMethod()  won't be visible since refering sub class
      //                           method with super class reference
   }
 }

Update

From Francis Upton I understood that anonySubClassMethod can be used within the anonymous class. So can i expect the java compiler to restrict the access specifier to private for anonySubClassMethod? Hope there will be a reason for this public specifier also. just curious.

Answer 1

The method can be called from within your anonymous class. And the more typical use of this construct is cases where you are implementing an interface (for a GUI listener for example), so the method will be known since it’s an implementation of the interface the caller is expecting.
