On inner classes:

First of all anytime I see more then one class in a .java file I tend to lump them together (i.e. make no distinction between nested and inner).  Now that being said here is a good example of something that is easier to read then either (yes it does get compiled into something very close to inner classes [not nested if I remember the jargon correctly] but no where near as ugly):

Foo.java:

public enum Foo
{
    ACK {
       public void doSomething(SomeClass arg)
       {
          do what ever for ACK
       }
    },
    BAR {
       public void doSomething(SomeClass arg)
       {
         do what ever for BAR
       }
    }
}

Fred.java:

public class Fred
{
     public void someMethod()
     {
        SomeClass sc=new SomeClass(...);
        Foo[] arr=new Foo[]{ACK,BAR};  // typing this for this example so being lazy on syntax

        for(Foo elem:arr)
            elem.doSomething(sc);
     }
}

and voila much more readable then putting a whole rats nest of stuff in the initialization of arr
     }
}
