Modifiers for anonymous inner classes and static nested classes

[janki tangeda]

Is it possible to declare any modifier for anonymous inner class?
If not, does it have any implicit modifiers?

For a static nested class what other modifiers can be specified?

Hi Everyone,

I have the same questions that were never answered in this old post (except I understand that anonymous classes are implicitly final (�15.9.5))...

1. Does anyone know if there is any way to specify a modifier (for example strictfp) on an anonymous class?

2. Am I correct in saying that the only modifiers that can be applied to static nested classes are: final, strictfp, coderanch, protected and private?

Thanks very much in advance...Catherine

I don't believe that's possible. Anonymous classes allow you to define only the class body (understanding that the reference will be automatically upcast, so you don't want to introduce anything that's not already declared in the supertype).

Note that static nested classes can be abstract...

class Enclosing {
  static abstract class Nested {
    abstract void meth1();
    void meth2() {
      System.out.println("meth2 implementation in Nested.");
    }
  }
  public static void main(String[] args) {
    SubEnclosing.SubNested nest = new SubEnclosing().new SubNested();
    nest.meth1();
    nest.meth2();
  }
}
 
class SubEnclosing extends Enclosing {
  class SubNested extends Nested {
    void meth1() {
      System.out.println("meth1 implementation in SubNest.");
    }
  }
}
