Anonymous Inner Class

[Sen George]

In the following code listing, please explain why the output " prAnon procedure" is not generated.

import static java.lang.System.out;
 
public class test_inner3 {
 
   void go() {
     out.println("  In go procedure");  
   }
 
 public static void main(String[] args) {
 
      test_inner3 mic = new test_inner3() {
 
       public void prAnon() {
        out.println("  prAnon procedure");
       }
     };
       
     mic.go();
  }
}

Sen,
Where does prAnon get called? It's just a method. If it doesn't get called, it doesn't print anything.

Just a guess on what might be causing the misunderstanding...

In the syntax for an anonymous inner class, the constructor call is followed by the anonymous class definition -- not the body of the constructor.

test_inner3 mic = new test_inner3() {
  //this is the body of the anonymous class
  //it is NOT the body of the test_inner3 constructor
};

So the code within the braces does not execute with "new."

How can I incorporate a call to invoke the method defined in an anonymous class?
