Cannot refer to a non-final variable inside an inner class defined in a different method

Question

Edited: I need to change the values of several variables as they run several times thorugh a timer. I need to keep updating the values with every iteration through the timer

Answer 1

If you want to change a value in a method call within an anonymous class, that "value" is actually a Future. So, if you use Guava, you can write

...
final SettableFuture myvalue = SettableFuture.create();
...
someclass.run(new Runnable(){

    public void run(){
        ...
        myvalue.set(value);
        ...
    }
 }

 return myvalue.get();
