        spanishGreeting.greet();
    }

    public static void main(String... args) {
        HelloWorldAnonymousClasses myApp =
            new HelloWorldAnonymousClasses();
        myApp.sayHello();
    }            
}

What calls the greet() method of the englishGreeting object? I'm confused..

EDIT

Thanks for your replies. I should have spotted that! I was trying to solve another query, which is:

In the example program on https://gist.github.com/bernii/5697073

In the code

this.wait.until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver webDriver) {
                System.out.println("Searching ...");
                return webDriver.findElement(By.id("resultStats")) != null;
            }
});

what calls the apply() method in the anonymous inner class?

EDIT

I have now asked my second query in a new Question.

Answer 1

In the part of the code shown below three instances of the HelloWorld interface are created:

    HelloWorld englishGreeting = new EnglishGreeting();         
    HelloWorld frenchGreeting = new HelloWorld() {
       //...
    };         
    HelloWorld spanishGreeting = new HelloWorld() {
       // ...
    };

And here some methods are called on those instances:

    englishGreeting.greet();
    frenchGreeting.greetSomeone("Fred");
    spanishGreeting.greet();

The french and spanish versions are created using an anonymous inner class. The english version is created from a local class declaration (EnglishGreeting). Note: you don't see local class declarations very often, it's a bit of a construed example.
